Which of the following numbers will replace the question mark (?) in the given series?
3, 21, 147, ?, 7203
Show answer & explanation
Correct answer: D
Explanation
The correct answer is Option 4 i.e. 1029.
Given series: 3, 21, 147, ?, 7203
The series follows this pattern:
3 × 7 = 21
21 × 7 = 147
147 × 7 = 1029
1029 × 7 = 7203
So, the missing term in the series is 1029.
