Re: replace the question mark
That is a good question.
In mathematics, you don't understand things. You just get used to them.
If it ain't broke, fix it until it is.
Always satisfy the Prime Directive of getting the right answer above all else.

I think it might be 42.

Re: replace the question mark
No, because 4 and 2 are the only two even digits that appear exactly 2 times, of course.
Though, what you said might be another reason for it.

Because I think that is what the creator of the puzzle was going for.

Re: replace the question mark
Might be.
Do you have any guess what the answer might be?

I just do not see what is so logical about one particular answer.

Re: replace the question mark
I'm going to make a hypothesis that the answer is a single digit positive integer.

Re: replace the question mark
I agree and by Bensfords rule it is most likely to be a 1.

Re: replace the question mark
Hi anonimnystefy,
I'm going to make a hypothesis that the answer is a single digit positive integer.
But I have an answer that is a single-digit negative integer.

Re: replace the question mark
Hi;
Before I forget my method for arriving at that negative answer, I'd better post it (not that I think it's the answer and logic that the author is looking for):

Re: replace the question mark
These hexagon number puzzles are common in so called IQ tests and in puzzle books. I don't think there is enough information in two diagrams to be certain about the third. And 6 very able members of the forum have come up with 6 alternative answers already, which is surely evidence that the puzzle is poorly formed. (Sorry Niharika if you made it up. 
)
If you did, please put us out of our misery and tell us.
But it had better be a good explanation.
