Correct option is D
Given:
5, 11, 24, 53, 106, 217
Logic: Previous number×2+(increasing sequence 1, 2, 3, 4, ...)
Applying the pattern:
5 × 2 + 1 = 11
11 × 2 + 2 = 24
24 × 2 + 3 = 51 (Given 53, incorrect)
51 × 2 + 4 = 106
106 × 2 + 5 = 217
The correct number at the fourth position should be 51, but the given number is 53.
Applying the pattern:
5 × 2 + 1 = 11
11 × 2 + 2 = 24
24 × 2 + 3 = 51 (Given 53, incorrect)
51 × 2 + 4 = 106
106 × 2 + 5 = 217
The correct number at the fourth position should be 51, but the given number is 53.
