Explanation

The differences between terms are: 24-17=7, 39-24=15, 62-39=23, 93-62=31. The differences are increasing by 8 (7, 15, 23, 31). The next difference should be 31+8=39. 93+39=132.

AI explanation

The series is based on a constant third level of differences. The first differences are 7, 15, 23, and 31, and the second differences are all 8, making the next first difference 39. Adding 39 to 93 gives the missing term of 132.
