B Correct answer
Explanation

The differences are: 121-116 = 5, 116-106 = 10, 106-91 = 15, 91-71 = 20. The next difference should be 25. 71 - 25 = 46.

AI explanation

The differences between consecutive terms are 5, 10, 15, and 20, forming a pattern of multiples of 5. The next difference in this sequence should be 25. Subtracting 25 from 71 gives 71 - 25 = 46. The missing number is 46.
