Question

In the following series, a set of numbers is progressing with a particular pattern. Can you deduce that pattern and find the missing set?

(2 + 6), (21 + 6), (58 + 6), (119 + 6), ??

Answer 1

Thsi has the pattern like :::

( ( n^3 - 6) + 6) ;;; start from n=2 onwards

((8-6) + 6)=====(2 + 6)

((27-6)+6) ======(21 + 6)

((64-6) + 6) =======(58 + 6)

((125-6) + 6 ) ======( 119 + 6)

((216- 6) + 6)===== (210 + 6 )
