Find the missing number (?) in the sequence 5, 11, 23, ?, 95, 191.
A
47
B
48
C
49
D
50
Correct Option:
A
Explanation
Each term is obtained by doubling the preceding term and adding 1: 5 × 2 + 1 = 11 and 11 × 2 + 1 = 23. Therefore, 23 × 2 + 1 = 47. The pattern continues with 47 × 2 + 1 = 95 and 95 × 2 + 1 = 191.
