I'm assuming the sequence is: -320, 80, -20, 5
Divide each term by the previous term to get the common ratio r
r = (term 2)/(term 1) = 80/(-320) = -1/4
r = (term 3)/(term 2) = -20/80 = -1/4
r = (term 4)/(term 3) = 5/(-20) = -1/4
No matter which term you pick (as long as it's not the first one) dividing it by the previous term leads to -1/4 or -0.25 as the common ratio
Answer: -1/4
