Question

Complete the series:
6, 21, 88, 445, (?)
​

Answer 1

Answer:

445

Step-by-step explanation:

‘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 ……..
