Determine the ratio of the geometric sequence: 1/10, -1/2, 5/

-1/5

1/5

-5

5

third option.

Step-by-step explanation:

By definition we know tht the geometric sequences has a common ratio, which is represented with r.

This ratio can be calculated by dividing a term by the previous term.

Therefore, keeping the information above on mind, you have that the ratio r  of the geometric sequence given in the problem, is the shown below:

The ratio of the sequence is -5

Step-by-step explanation:

The given geometric series is ;

The ratio of the geometric sequence is given by;

We simplify to get;

x/3-10=8

x/3=18

x=48
