Answer:
-1/4 if you prefer the answer written as a fraction.
-0.25 is you prefer the answer written as a decimal.
Step-by-step explanation:
Common ratio of a geometric sequence can be found by doing term divided by previous term.
That is you could do:
80/-320
or
-20/80
or
5/-20
If all these ratios are not equal, it isn't a geometric sequence and does not have a common ratio.
Let's see what these reduce to:
80/-320=1/-4 =-1/4 or -0.25
-20/80=-1/4 or -0.25
5/-20=1/-4=-1/4 or -0.25
So the common ratio is -0.25 or yo you can write it as -1/4.
