I got 6 too, but my logic was that the number on the left was being multiplied by 8,7,6,5,... but your approach is superior because it works even if people don't realize that the left side skips from 5 to 3.

f(x)=x^2-x; or: f(x)=x-1) are correct...in that both get you to the correct answer.

BUT, f(x)=x^2-x is the absolutely correct response!

38. It could be that, too

since 3 is a prime number and you can't divide anything by it. It's a trick question, but mathematically the answer is 6 but there are about 5 different ways to make it work. You can look at it as a regressive formula, or also as simple addition and subtraction.

49. Trick question. 3=3

First of all, they're trying to trick you by saying 9=72, 8=56 and so on into order for you to recognize a pattern n=n*(n-1). But that isn't how the equality relationship works. n=n for all n. They know that people will over think it and interpret it as a congruence relationship. But that isn't technically what they wrote.


Then they're also trying to trick you by skipping from 5 to 4, so that you get out of sequence and answer 9 instead of 6.

8 = 56 then (+16 = 72)
7 = 42 then (+14 = 56)
6 = 30 then (+12 = 42)
5 = 20 then (+10 = 30)
4 = 12 then (+8 = 20)
3 = 6 then (+6 = 12)
2 = 2 then (+4 = 6)
1 = 0 then (+2 = 2)

62. There is no single solution without further info

It could be 6 if you assume the formula is X * (X-1)

It would equal null if it's X * the numeral below X (there is none below 3, not even zero)

Not sure where folks are getting 9.

65. Can also be 14 actually.

Formula could also be (Previous value of x) -(x+x)

So
8=56
7=42 or 56-(7+7)
6=30 or 42-(6+6)
5=20 or 30-(5+5)
3=14 or 20-(3+3)

9 = 72 (9 x 8 = 72)

3 = 21 (3 x 7 = 21)

66. It is 12 because...


On the equals side of the list of equations, starting with 20 and going up, the difference between each starts with ten, (30-20) and increases by two.

Using that logic, if we move down from 20 on the same side, and figure the answer is the difference between 20 and 8, we end up with 12.

Maybe there's more than one answer, but that's one.

124. The difference between programming and math

In code, "x=x+1" uses a single equals sign as an assignment operator, meaning the right side is evaluated and the resulting value then assigned to the left side. But the expression x=x+1 will never be true in arithmetic. You can do that with a programming variable, but you can't arbitrarily make 9 = 72 in math; it's an invalid operation.

Essentially the only relevant part of the so-called "math" quiz is the last line: 3 = ??, where the answer is obviously 3. Everything above that point is meaningless. If they want to call 3.14 = cherry pie, they can call it a puzzle or riddle.

125. So you arbitrarily declare most of the quiz 'meaningless'?

A quiz is not a formal examination; it doesn't mean that what appears in it must be something you could write in a mathematical paper. Quizzes can include puzzles.

If you really want to say that the answer must be something that is equal to the '3' on the left of the equals sign, then there are an infinite number of 'correct' solutions; 4-1, 25-22, -1 * -3, the real cube root of 27, etc. Which are all more interesting than putting '3' there.

As I said, 9 will never equal 72, even in extremely large cases of 9. And yes, you can enter anything on the right-hand side of the equals sign that evaluates to the value on the left. That doesn't change my point.

If every different expression that is equal to three is allowed as an answer, what type of infinity is being discussed? Countable, Uncountable, ... ?

107. But you haven't used the 9 in the top line

You've calculated the '72' from all the numbers on the left below it, but ignored the '9' entirely. Not as elegant as just using the number on the left of each '=' to get the number on the right (ie the 'n=n(n-1)' formula most have used), I think.

There is no 4 in the pattern. You can infer it, but strictly speaking without it the other answers lack symmetry. This is a code, and the "=" does not have the same function as it would in a math equation.

ETA: Forgot to address the 9. That is only used to continue the pattern to 10=90.

136. It doesn't need to be a strict sequence to show a pattern

so a '4=12' line is unnecessary. I agree that it's a code, and '=' does not have the function it would in an equation; but, in fact, by putting it in your form, you make it less of a code. If it's a code, we can say "the '=' sign means 'multiplied by the number one less than itself is'". Your interpretation means you have to use each number on the right in 2 statements.

Yes it means you have to use the number in two statements - that is what turns it into a definitive pattern.

Response to fried eggs (Original post)

Fri Jun 7, 2013, 11:29 PM

86. I am the ONLY GENIUS here. The Answer is 24. Here is why.

 

If the numbers on the left side of each equal sign progressed from 9 to 3, as in 9,8,7,6,5,4,3, this answer wouldn't work. However, they "skip" the 4 because the sequence 8,7,6,5 ends at 5. That's why that sequence is colored BLUE. The pattern in the BLUE sequence of numbers is what everybody in this thread is saying: left number "equals" left number minus 1 multiplied by left number.

Also, those who are saying that the equals sign is always an equals sign and therefore "3=3" is the answer are missing the point that every single other "equation" evaluates to "false". If you want to be logical about it, then, you would say your answer is 3 "equals" anything OTHER than 3.

Now, the red "equations" are an entirely different sequence. That's why they're colored red. There is NO REASON to color the "3=??" one red other than to distinguish it from the fact that it is completely UNREALTED to the blue ones and paired up with the only OTHER red one: The "9=72" one. Coloring "3=??" red makes it clear that there is no "skipping" of the 4.

Thus we only have two "equations" to work with.

9=72
3=??

The only relationship between numbers that we have to work with are 9 and 72,
Now 9 times 8 equals 72.
Therefore 3 times 8 equals 24.

But why multiply by 8? Because if we're going to assume that this is a sequence with some kind of logic behind it, then this makes both of these terms, namely term 3 and term 9, related only with whatever relationship we can find between 9 and 3. The relationship between 9 and 3 must also agree with our previous answer, though, when applied to the number 72.

Notice that 9 divided by 3 equals 3: Therefore 72 divided by 3 equals 24. Again, we arrive at 24.

QED.

but I don't think the graphic provides enough information to solve the problem. Every answer requires making assumptions that are not explicitly stated. 6 assumes the author left out the 4 to trick us; 9 assumes the author didn't intend for the left side to follow a sequence; and 24 assumes the colors are intentionally different. So I guess we'll never really know. lol

89. By roughly the same logic, why not 21?

The only difference being that the for the red equations, the answer on the left is the sum of the digits on the right?

9=72 (9=7+2)
3=21 (3=2+1)

I guess this solution would also leave the question, though, of why wouldn't "12" be a correct answer

If this problem is asking people to look for patterns and apply them to find an answer, a number of different patters can be found leading to a number of different answers without more information.

If the pattern is "sum of the digits", then you're lead to an ambiguous solution. It can be EITHER 12 or 21, there's no way to know. The same thing goes for people saying it's 6 or 9, "depending on"... If you have an ambiguous solution, you don't have the solution.

123. Since the series is broken, and because 9 and 3 are

differentiated by having the same, different color. I use the red formula, which is x*8=y and arrive at 24 as the answer. Were it not for the color difference, I would assume the series x*(x-1) = y and say 6.

But, due to the color difference, 9 and 3 are marked as not part of the series. The missing 4=12 further indicates that it is not the series we are looking at but the red colored numbers.

However, since the equation itself is invalid as presented, I would be annoyed at the question and would refuse to answer, which is the correct answer, really.

On Error Resume Next
If color = red Then y = x*(x-1)
Elseif color = blue Then y = x*8

147. There is, of course, no right answer and the psychology types here should...

recognize this as one of those tests which doesn't look for a correct answer, but for your approach to an answer. Dunno if people are still using this stuff in job interviews, but it is interesting.

"5=20" is meaningless except as a definition, and we're not told what is being defined and where the definition is being used. It could e part of some odd computer code where that sort of identity is common but usually using more sensible variables.

So, I jumped on 6, simplistically using the x-1 thing and that is one acceptable answer. However, it is simplistic and obvious and those of us using it are on the low end. Others, coming up with other rational and more elegant solutions are also "correct" but show more creativity in their answers.

If I were using this as a hiring tool, I'd put those who answered "6" in one "acceptable" pile, but some of the other answers might go into the "callback" pile.

(While fully understanding, however, that brilliant flights of fancy often get in the way of actually doing the job.)

150. What happened to agent Mike?

Did he view one too many kitty videos, and go all granola on the bureau?

153. Not possible, insufficient info available. IF color matters, 24. Or 6. Or ???

The sequencing does not specify if the differing colors of red and blue have any bearing on the actual calculation. If not, the answer would be 6...but that can't be said for certain.

If color does matter, 24 would be a reasonable guess, if the "invisible" value 8
in the single other red equation of 9 =72 applies to all other red equations. But that's unknown as well -- there are only two red equations visible -- not enough info to establish any pattern...the answer to 3=??? could really be anything.

159. The correct answer is 9

We have to consider each line number...
number x 3+number x line# =....
Line 5: 9*3+9*5 = 72
Line 4: 8*3+8*4 = 56
Line 3: 7*3+7*3 = 42
Line 2: 6*3+6*2 = 30
Line 1: 5*3+5*1 = 20
Line 0: 3*3+3*0 = 9

163. The answer is NOT patterns, per se...

It is actually an equation, f(x)=x^2-x (x squared minus x) ; or, if factored-out: f(x)=x-1)

ALL of the pattern suggestions are WRONG!

The correct answer, like it, or not, is: 6

f(8)=8*8-8=56
f(7)=7*7-7=42
f(6)=6*6-6=30
f(5)=5*5-5=20
f(3)=3*3-3=6


It is NOT that this took a "genius", it's more than one had to go back and re-visit how to generate an equation for ALGEBRA!

You're welcome!
