Answer:
50 is the answer.
Step-by-step explanation:
We have, and common ratio d=2/5.
So, the general form of the geometric series is , for 'n' is from 1 to infinity.
Hence, the sum in sigma form = , where n goes from 1 to infinity.
Now, the infinite sum of geometric series =
i.e. = 50
Hence, the sum which will be the upper limit is 50
