Back to paper

Select the number that can replace the question mark (?) in the following series.

126, 217, 344, ?

Show answer & explanation

Correct answer: A

Explanation

The correct answer is option 1 i.e 513.

Understanding

Given series: 126, 217, 344, ?

The series follows the pattern:

126 = 53 + 1

217 = 63 + 1

343 = 73 + 1

So the next term will be 83 + 1 = 513.

So the missing term is 513.
