If $\"\"$ , then the infinite geometric series $\"\"$ converges,

its sum is $\"\"$ .

$\"\"$

The infinite geometric series is $\"\"$

The first term of the series, $\"\"$ .

The second term of the series, $\"\"$ .

The common ratio ,

$\"\"$

$\"\"$ .

Since $\"\"$ , the series is converges.

The sum is $\"\"$ .

Substitute the values of $\"\"$ and $\"\"$ in above formula.

Sum $\"\"$
