Select the number from among the given options that can replace the question mark (?) in the following series.
14, 33, 71, 147, 299, ?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is Option 4 i.e. 603.
Given series: 14, 33, 71, 147, 299,?
The series follows this pattern:
14 × 2 + 5 = 28 + 5 = 33
33 × 2 + 5 = 66 + 5 = 71
71 × 2 + 5 = 142 + 5 = 147
147 × 2 + 5 = 294 + 5 = 299
299 × 2 + 5 = 598 + 5 = 603
So, the next term in the series is 603.
