Show answer & explanation
Correct answer: B
Key idea: each term is obtained by multiplying the previous term by 2 and then adding 1.
11 × 2 + 1 = 23
23 × 2 + 1 = 47 (expected), but the series shows 46 here
47 × 2 + 1 = 95, and 95 × 2 + 1 = 191
Therefore, 46 is incorrect because it should be 47 according to the rule ×2 + 1.
