3times3times3=27

4times4times4=64

8, 27, 64, 125 ...............

Example 5

A sequence of power of 10 (or indices of 10).

 10^1 = 10 10^2 = 10times10 = 100 10^3 = 10times10times10 = 1000 10^4 = 10times10times10times10 = 10,000

10, 100, 1000, 10,000 ..........

These are all multiples of 10.

Example 6
