Show answer & explanation

Correct answer: C. 24

Explanation

The terms follow n² + 1: 2²+1 = 5, 3²+1 = 10, 4²+1 = 17, 5²+1 = 26, 6²+1 = 37, 7²+1 = 50, 8²+1 = 65. The fourth term should therefore be 26, not 24. Hence the wrong term is 24.पद n² + 1 के क्रम में हैं: 2²+1 = 5, 3²+1 = 10, 4²+1 = 17, 5²+1 = 26, 6²+1 = 37, 7²+1 = 50, 8²+1 = 65। अतः चौथा पद 26 होना चाहिए, 24 नहीं। इसलिए गलत पद 24 है।
