Answer 1

Answer:

Its ‘445’.

‘n’ th term in sequence is the sum of ‘n-1’ th natural number and product of previous term (i.e., ‘n-1’ th term) with ‘n-1’ th natural number.

1 is the first term and thereafter the sequence is,

(1×1) + 1 = 2

(2×2) + 2 = 6

(6×3) + 3 = 21

(21×4)+4 = 88

(88×5)+5 = 445 ……..

Answer 2

Answer:

The next term will be 2676

2 × 2 + 2 = 6

6 × 3 + 3 = 21

21 × 4 + 4 = 88

88 × 5 + 5 = 445

so, 445 × 6 + 6 = 2676
