Which number will replace the question mark(?) in the following series?
82, ?, 119, 142, 168, 197
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 99.
Given series: 82, ?, 119, 142, 168, 197
The series follows the pattern:
197 - 168 = 29
168 - 142 = 26
142 - 119 = 23
119 - x = 20 ⇒ x = 99
99 - 82 = 17
So, the missing term in the series is 99.
