Which of the following numbers will replace the question marks (?) in the given series?
119, 117, 114, 109,? , 91, ?, 61
Show answer & explanation
Correct answer: B
Explanation
The correct answer is Option 2 i.e. 102, 78.
Given series: 119, 117, 114, 109,? , 91, ?, 61
The series follows this pattern:
119 - 2 = 117
117 - 3 = 114
114 - 5 = 109
109 - 7 = 102
102 - 11 = 91
91 - 13 = 78
78 - 17 = 61
So, the next terms in the series are 102 and 78.
