Replace the incorrect term by the correct term in the given sequence 3, 2, 7, 4, 13, 10, 21, 18, 31, 28, 43, 40 where odd terms and even terms follow the same pattern.

Correct Answer: (A) 0

The odd terms form the sequence 3, 7, 13, 21, 31, 43 with differences $+4, +6, +8, +10, +12$. The even terms must follow the exact same differences. Working backward from 40: $40 - 12 = 28$, $28 - 10 = 18$, $18 - 8 = 10$, $10 - 6 = 4$, and $4 - 4 = 0$. Therefore, the incorrect term 2 should be replaced by 0.
