Show answer & explanation

Correct answer: C. 35

Explanation

The terms are squares with 1 alternately added and subtracted: 1²+1 = 2, 2²−1 = 3, 3²+1 = 10, 4²−1 = 15, 5²+1 = 26. The next term is 6²−1 = 35.प्रत्येक पद किसी संख्या का वर्ग है जिसमें बारी-बारी से 1 जोड़ा और घटाया गया है : 1²+1 = 2, 2²−1 = 3, 3²+1 = 10, 4²−1 = 15, 5²+1 = 26। अगला पद 6²−1 = 35 होगा।
