Which number will replace the question mark (?) to complete the given series?
5, 7,11, ?, 35, 67
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1. i.e. 19.
Given Series : 5, 7,11, ?, 35, 67
Logic : Adding power of 2
5 + (2)1 = 7
7 + (2)2 = 11
11 + (2)3 = 19
19 + (2)4 = 35
35 + (2)5 = 67
Hence, 19 is the correct answer.
