Which of the following numbers will replace the question mark (?) in the given series?
420, 462, 506, ?, 600, 650, 702
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 552.
Given series: 420, 462, 506, ?, 600, 650, 702
The series follows this pattern:
420 + 42 = 462
462 + 44 = 506
506 + 46 = 552
552 + 48 = 600
600 + 50 = 650
650 + 52 = 702
So, the missing term in the series is 552.
