Correct Answer: 365


Solution : Given:
2, 5, 14, 41, 122, ?

The pattern is as follows –
(2 × 3) – 1 = 6 – 1 = 5
(5 × 3) – 1 = 15 – 1 = 14
(14 × 3) – 1 = 42 – 1 = 41
(41 × 3) – 1 = 123 – 1 = 122
(122 × 3) – 1 = 366 – 1 = 365

So, the missing number of the series is 365. Hence, the second option is correct.
