C Correct answer
Explanation

The sequence follows the pattern n^2 + 1: 2^2+1=5, 3^2+1=10, 4^2+1=17, 5^2+1=26 (not 24), 6^2+1=37, 7^2+1=50, 8^2+1=65. Thus, 24 is the wrong term.

AI explanation

The series follows a pattern of adding consecutive odd numbers. The sequence of additions is 5 + 5 = 10, 10 + 7 = 17, 17 + 9 = 26, 26 + 11 = 37, 37 + 13 = 50, and 50 + 15 = 65. The term 24 breaks this pattern because the correct term at that position should be 26, making 24 the wrong term.
