Determine the common ratio of the geometric progression 2, 4, 8, 16.

To find the common ratio of a geometric progression, we divide any term by the previous term.

In this case, we can divide 4 by 2, 8 by 4, and 16 by 8 to find the common ratio:

4/2 = 2
8/4 = 2
16/8 = 2

Therefore, the common ratio of the geometric progression 2, 4, 8, 16 is 2.

The common ratio of a geometric progression is the ratio of any two consecutive terms. In this case, the common ratio is:

4 / 2 = 2
8 / 4 = 2
16 / 8 = 2

Therefore, the common ratio of the geometric progression is 2.
