Question
What should come in place of (?) question mark in the given number series. 3, 8, 15, 24, ?, 48
Solution
Look at the pattern: 3 = 1² + 2 8 = 2² + 4 This is not fitting properly, so check differences: 8 - 3 = 5 15 - 8 = 7 24 - 15 = 9 The differences are consecutive odd numbers: 5, 7, 9, 11, 13 So next: 24 + 11 = 35 35 + 13 = 48 Answer: 35
