Which of the following numbers will replace the question mark (?) in the given series?
10, 0, 20, 10, 30, 20, 40, 30,?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is Option 1 i.e. 50.
Given series: 10, 0, 20, 10, 30, 20, 40, 30,?
The series follows this pattern:
1. 10, 20, 30, 40,?
10 + 10 = 20
20 + 10 = 30
30 + 10 = 40
40 + 10 = 50
2. 0, 10, 20, 30
0 + 10 = 10
10 + 10 = 20
20 + 10 = 30
So, the next term in the series is 50.
