Which of the following numbers will replace the question mark (?) in the given series?
23, 50, 108, 228, ?, 964
Show answer & explanation
Correct answer: A
Explanation
The correct answer is Option 1 i.e. 472.
Given series: 23, 50, 108, 228, ?, 964
The series follows this pattern:
23 + 27 = 50
50 + (27 × 2 + 4) = 50 + 58 = 108
108 + (58 × 2 + 4) = 108 + 120 = 228
228 + (120 × 2 + 4) = 228 + 244 = 472
472 + (244 × 2 + 4) = 472 + 492 = 964
So, the missing term in the series is 472.
