The odd one out

[Gus Molloy]

I have been presented a series of numbers and asked which is the odd one out and why. I haven’t been able to figure this out and keen on some thoughts. The numbers are:

3, 4, 13, 14, 40, 46

Thanks

Commonly this kind of question does not have one correct answer. You may be able to give a reason for choosing any of them. The best that can be hoped is that there is one "obvious" answer.

I see nothing obvious, so I would not spend any more time on it, unless there is some context that might hint at what the author might be thinking.

While I agree with Prof. Peterson that there is no correct answer, there is only one of those numbers that has a rational square root.

The answer for your homework is 46? Why?

3 and 4 is a difference of +1
4 and 13 is 3*4+1
13 and 14 is a difference of +1
14 and 40 is 3*14-2
Therefore, 46 has the greatest deviation and little in common with 40.
