Now, there is an interesting thing...

That was a very interesting way of looking at it, and it took a lot of intelligence to come up with that answer... But, it isn't the way that I came up with the answer for that problem.

If you analyze the number sequence by differences between each number and the next, you get...

9 7 8 6 7 5 6 3

Difference between 9 and 7 is two
Difference between 7 and 8 is one
Difference betweeen 8 and 6 is two
Difference between 6 and 7 is one
Difference between 7 and 5 is two
Difference between 5 and 6 is one
Difference between 6 and 3 is three

Thus, 3 would again happen to be the answer, in this case, because it is the difference in this sequence.

But, what if the two completely different ways of deriving the 'correct' answer both took intelligence but one of the answers was a wrong answer relative to the IQ test?

Do you think there might be a way of looking at this number sequence that might be even more creative than both of our methods were, but be the technically 'wrong' answer?

Wouldn't that mean the person coming up with the method had shown incredible intelligence - coming up with a relationship between the numbers that was far more creative than the one the writer intended?

Would that make the person who got the wrong answer stupid, or even more intelligent than the writer of the problem?

(Oh, and here's your lolipop...)
