Which of the following numbers will replace the question mark (?) in the given series?
12, 60, 20, 100, 60, 300, 260, ?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 1300.
Given series: 12, 60, 20, 100, 60, 300, 260,?
The series follows this pattern:
12 × 5 = 60
60 - 40 = 20
20 × 5 = 100
100 - 40 = 60
60 × 5 = 300
300 - 40 = 260
260 × 5 = 1300
So, the next term in the series is 1300.
