Which of the following numbers will replace the question mark (?) in the given series?
100, 80, 63, 49, 38, 30,?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is Option 1 i.e. 25.
Given series: 100, 80, 63, 49, 38, 30,?
The series follows this pattern:
100 - 20 = 80
80 - (20 - 3) = 80 - 17 = 63
80 - (17 - 3) = 63 - 14 = 49
80 - (14 - 3) = 49 - 11 = 38
80 - (11 - 3) = 38 - 8 = 30
80 - (8 - 3) = 30 - 5 = 25
So, the next term in the series is 25.
