Which of the following numbers will replace the question mark (?) in the given series?
3, 11, 27, 59,?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is Option 1 i.e. 123
Given series: 3, 11, 27, 59, ?
The series follows this pattern:
3 + 8 = 11
11 + (8 × 2) = 11 + 16 = 27
27 + (16 × 2) = 27 + 32 = 59
59 + (32 × 2) = 59 + 64 = 123
So, the next term in the series is 123.
