Answer 2

We can recall that:

A sequence is defined as a set of integers arranged in a specific order. A series, on the other hand, is defined as the sum of a sequence's elements.

$4\times1^{3}=5\\ 5\times2+2^3=18\\18\times3+3^3=81\\81\times4+4^3=388\\388\times5+5^3=2065$

Hence, the series is $4,5,18,81,388,2065.$
