Which of the following numbers will replace the question mark (?) in the given series?
235, 271, ?, 349, 391, 435
Show answer & explanation
Correct answer: C
Explanation
The correct answer is Option 3 i.e. 309.
Given series: 235, 271, ?, 349, 391, 435
The series follows this pattern:
235 + 36 = 271
271 + 38 = 309
309 + 40 = 349
349 + 42 = 391
391 + 44 = 435
So, the missing term in the series is 309.
