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.
8/5 + 32/25 + 128/125 + ...
r = 128/125 ÷ 32/25 = 128/125×25/32 = 4/5
r = 32/25 ÷ 8/5 = 32/25 × 5/8 = 4/5
In the series is less than 1. So the series is convergent.
