Answer:
The common ratio is -2.5
The next three terms are;
-125, 312.5 and -781.25
Step-by-step explanation:
Here, firstly we want to determine the common ratio 
To
do this, we have to divide the succeeding term by the preceding term
We have this as;
50/-20 = -20/8 = -2.5
Now, to get the next terms,
we multiply the given last term by the common ratio 
That will be;
50 * -2.5 = -125
next is to multiply this by the common ratio 
That will be;
-125 * -2.5 = 312.5
And lastly, we have 
312.5 * -2.5 = -781.25
