# What is the 4th term in the sequence of cube numbers?

A cube number, also known as a perfect cube, is number which is the cube of an integer.

If we consider positive perfect cubes, then the first 4 are:

1^3 = 1

2^3 = 8

3^3 = 27

4^3 = 64

If we consider non-negative perfect cubes, we must include 0. We then have:

0^3 = 0

1^3 = 1

2^3 = 8

3^3 = 27

Since the cube of a negative number is negative, we also have negative cube numbers. For example, (-4)^3 = -64 so -64 is a perfect cube.
