B Correct answer
Explanation

The differences between consecutive terms in the series are 192, 96, and 48. Since each difference is exactly half of the preceding one, the next difference must be 48 / 2 = 24. Subtracting 24 from 115 gives the missing number, 91.

AI explanation

The differences between consecutive terms are 192, 96, 48, 24 and 12, forming a pattern where each difference is halved. Subtracting 24 from 115 gives the missing number, which is 91.
