Which of the following numbers will replace the question marks (?) in the given series?
156, 144, 133, 123, 114, ?, 99, ?, 88, 84
Show answer & explanation
Correct answer: D
Explanation
The correct answer is Option 4 i.e.106, 93.
Given series: 156, 144, 133, 123, 114, ?, 99, ?, 88, 84
The series follows this pattern:
156 - 12 = 144
144 - 11 = 133
133 - 10 = 123
123 - 9 = 114
114 - 8 = 106
106 - 7 = 99
99 - 6 = 93
93 - 5 = 88
88 - 4 = 84
So, the missing terms in the series are 106 and 93.
