The terms with which the given series starts is `(1/2), (1/4), (1/8)`

The first term of the series is `1/2` . The ratio between two consecutive terms is `(1/8)/(1/4) = (1/4)/(1/2) = 1/2` . As the ratio is the same, this is a geometric series with first term `1/2` and common ratio `1/2` . As the number of terms of which the sum has to be determined is not given, the sum of infinite terms of the series has been determined.

This is equal to `(1/2)/(1 - 1/2) = 1`

**The sum of infinite terms of the series `(1/2), (1/4), (1/8)... ` is 1.**
