B Correct answer
Explanation

The pattern is: 7 + 5 = 12; 12 * 2 + 1 = 25; 25 - 3 = 22; 22 * 2 - 1 = 43; 43 - 11 = 32. Alternatively, looking at alternating terms: 7, 25, ? (diff 18, 18) -> 43; 12, 22, 32 (diff 10, 10). The missing term is 43.

AI explanation

This is an alternating addition and subtraction series. The pattern is (7 + 5 = 12), then (12 + 13 = 25), (25 - 3 = 22), and the next step is addition of 21 (22 + 21 = 43). Verifying the logic, the last step is 43 - 11 = 32, making 43 the missing term.
