I have this sequence:
24, 63, 10, 48, 35, 72, 44....
The next number is
80.
How is this the correct answer?

$\begingroup$ All of those are composite numbers: 4x6, 7x9, 2x5, 6x8, 5x7, 8x9, 4x11 (and also 8x10). That might have something to do with it. $\endgroup$ – Levieux Feb 13 '17 at 12:41

$\begingroup$ More than that: most of them are of the form n^2-1. 25, 64, 11, 49, 36, 73, 45, 81. $\endgroup$ – Gareth McCaughan♦ Feb 13 '17 at 12:59

One possible answer that works for finding the next number, but not the entire sequence is
The number sequence is generated in pairs with a descending sum
24 + 39 = 63
10 + 38 = 48
35 + 37 = 72
This would imply the next number in the sequence is
44 + 36 = 80
