Which of the following numbers will replace the question mark (?) in the given series?
109, 122, 148, ?, 239, 304
Show answer & explanation
Correct answer: D
Explanation
The correct answer is Option 4 i.e. 187
Given series: 109, 122, 148, ?, 239, 304
The series follows this pattern:
109 + 13 = 122
122 + 26 = 148
148 + 39 = 187
187 + 52 = 239
239 + 65 = 304
So, the missing term in the series is 187.
