Correct Answer: 60
Solution :
Given:
27, 29, ?, 182, 730, 3652
Multiply the previous term by the consecutive natural numbers and then add 2 to the resultant to get the next term in the series.
(27 × 1) + 2 = 27 + 2 = 29
(29 × 2) + 2 = 58 + 2 = 60
(60 × 3) + 2 = 180 + 2 = 182
(182 × 4) + 2 = 728 + 2 = 730
(730 × 5) + 2 = 3650 + 2 = 3652
So, 60 is the missing number of the series. Hence, the fourth option is correct.
