Show answer & explanation

Correct answer: D. 129

Explanation

Differences follow +1, −2, +3, −4, +5: 125 → 126 → 124 → 127 → 123 → 128. So the last term should be 128, and 129 is wrong.अंतर +1, −2, +3, −4, +5 के क्रम में हैं: 125 → 126 → 124 → 127 → 123 → 128। अतः अंतिम पद 128 होना चाहिए, और 129 गलत है।
