Correct Answer: 1151


Solution : Given:
4, 13, 41, 126, 382, ?

Multiply the terms by 3 and add consecutive natural numbers to the resultant to get the following terms.
(4 × 3) + 1 = 12 + 1 = 13; (13 × 3) + 2 = 39 + 2 = 41; (41 × 3) + 3 = 123 + 3 = 126; (126 × 3) + 4 = 378 + 4 = 382; (382 × 3) + 5 = 1146 + 5 = 1151

So, the required missing number is 1151. Hence, the third option is correct.
