D Correct answer
Explanation

The series alternates between positive and negative values. The absolute values are 60, 52, 44, 36, 28, which decrease by 8 each time. The signs are +, -, +, -, +, so the next term should be negative and follow 28 - 8 = 20. Thus, -20.

AI explanation

The numbers follow a pattern of an arithmetic progression with an alternating sign for each consecutive term. Ignoring the signs, the absolute values decrease by 8, as seen from 60 to 52, 44 to 36, and 36 to 28. Continuing this pattern, we subtract 8 from 28 to get 20, and because the signs alternate, we make it negative. The result is -20.
