C Correct answer
Explanation

The series follows the pattern n^2 + 1: 1^2+1=2, 2^2+1=5, 3^2+1=10, 4^2+1=17, 5^2+1=26, 6^2+1=37. The term 24 is incorrect; it should be 26.

AI explanation

The pattern adds consecutive odd numbers to each term, with the differences being 5 - 2 = 3, 10 - 5 = 5, 17 - 10 = 7, and 37 - 24 = 13. The difference after 17 should be 9, meaning the fifth term should be 17 + 9 = 26 instead of 24.
