Next number of the series is 205.
Explanation :
The relation of the given sequence is x^3 - 2x + 1.
Substitute x = 1, 2, 3....
If x = 1, then
= 1^3 - 2(1) + 1.
= 1 - 2 + 1 =0.
x = 2.
= 2^3 - 2(2) + 1.
= 8 - 4 + 1.
= 5.
Similarly x = 6, then
= 6^3 - 2(6) + 1 .
= 216 - 12 + 1.
= 205.
Therefore the series is 0, 5, 22, 57, 116, 205.
hope it helps
