## How to Find Infinite Geometric Series Calculator?

Infinite geometric series is an infinite progression with first term a_{1} and common ratio (r) and if the value of r lies between 0 and 1, that is 0 < r < 1 then we can calculate the sum of the infinite geometric series with the help of below-given formula:

S_{∞} = a_{1} / (1 - r)

**Solved Example:**

Calculate the sum of given infinite geometric series:

16, 8, 4, 2, 1, 0.5, ................

**Solution:**

In the given geometric series

The value of first term a_{1} = 16

And the common ratio r = 0.5

So, the sum of infinite series is = S_{∞} = a_{1} / (1 - r)

S_{∞} = 16 / (1 - 0.5)

S_{∞} = 16 / 0.5

S_{∞} = 32

Thus, the sum of given infinite series is 32.
