Which number will replace the question mark (?) in the following series?
182, 132, 90, 56, ?, 12, 2
Show answer & explanation
Correct answer: A
Explanation
The correct answer is Option 1 i.e. 30.
Given series: 182, 132, 90, 56, ?, 12, 2
The series follows this pattern:
182 - 50 = 132
132 - (50 - 8) = 132 - 42 = 90
90 - (42 - 8) = 90 - 34 = 56
56 - (34 - 8) = 56 - 26 = 30
30 - (26 - 8) = 30 - 18 = 12
12 - (18 - 8) = 12 - 10 = 2
So, the missing term in the series is 30.
