What should come in place of (?) in the given series?
4, 13,?, 58, 94, 139, 193
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 31.
The series follows this pattern:
4 + (9 × 1) = 4 + 9 = 13
13 + (9 × 2) = 13 + 18 = 31
31 + (9 × 3) = 31 + 27 = 58
58 + (9 × 4) = 58 + 36 = 94
94 + (9 × 5) = 94 + 45 = 139
139 + (9 × 6) = 139 + 54 = 193
So, the missing term in the series is 31.
