7 x 2 + 1 = 15
15 x 2 + 1 = 31
31 x 2 + 1 = 63
63 x 2 + 1 = 127

Given:
Series
1, 2, 3, 7, 15, 24, 51, 67, ?
To Find:
What number will replace the ‘?’
Solution:
Understand the series
1
1 + 1² = 2
2 + 1³ = 3
3 + 2² = 7
7 + 2³ = 15
15 + 3² = 24
24 + 3³ = 51
51 + 4² = 67
Using the same logic now 4³ should be added to last number
67 + 4³ = 131
Hence Next number in the series is 131
131 replaces ? in the given sequence: 1, 2, 3, 7, 15, 24, 51, 67, ?
