Answer:
A
Step-by-step explanation:
A series is said to be convergent if |r| < 1. Where r is the common ratio of the series.
If |r| ≥ 1 then the geometric series diverges.
-5 + 25 - 125 + ..
r = -5/25 = -1/5
r = 25/-125 = -1/5
|r| = 1/5
In the series is |r| less than 1. So the series is convergent.
