For this case we have a geometric sequence of the form:

-125, -25, -5, -1

We want to find the common ratio between each term.

To do this, the next term between the previous term.

We have then:

$\frac {-25} {- 125} = \frac {1} {5}\\\frac {-5} {- 25} = \frac {1} {5}\\\frac {-1} {- 5} = \frac {1} {5}\\$

Therefore, the common ratio between each term is:

$r = \frac {1} {5}$

the common ratio of the sequence is:

$r = \frac {1} {5}$
