Is that a "riddle", or is it based on mathematics?

I'd say both.

Hint: Don't view the listing as an ordered set; just compare values. (I might even say, "comPAIR" values.)

Once you recognize a relationship, you will know which number is missing.

Where is the gap in the sequence "2, 4, 5, 7, 8, 25, 64"? The location being filled will very likely affect the so-called "best" choice of value for filling the gap.

When you reply, please include a clear listing of your thoughts and efforts so far. Thank you!
