Which number will replace the question mark(?) in the following series?
37, ?, 61, 78, 97, 120, 149
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 48.
Given series: 37, ?, 61, 78, 97, 120, 149
The series follows the pattern:
37 + 11 = 48
48 + 13 = 61
61 + 17 = 78
78 + 19 = 97
97 + 23 = 120
120 + 29 = 149
So, the missing term in the series is 48.
