Answer:

The sum of the given n term sequence is 0.5555555….

Given:

The series is 0.5, 0.05, 0.005,..

To find:

The sum of the series

Solution:

Since the last number or the nth term is not given,

Add the first two terms, 0.5 + 0.05 = 0.55

Add third term to the sum, 0.55 + 0.005 = 0.555

By adding the terms, the sum of the series would be 0.5555555….

Result:

The sum of the given n term sequence is 0.5555555….
