Answer 2

Answer:

The missing number would be 326.

Step-by-step explanation:

Given sequence,

1, 2, 5, 16, 65.......

By analysing the sequence,

We observed that,

1 × 1 + 1 = 2

2 × 2 + 1 = 5

5 × 3 + 1 = 16,

16 × 4 + 1 = 65

Thus, by following the pattern, the next term would be,

65 × 5 + 1 = 326

Hence, the missing number would be 326.
