$\"\"$

The sum of an infinete geometric series is $\"\"$ , with $\"\"$ ,

Where $\"\"$ is first term and r is common ratio.

The values are $\"\"$ .

$\"\"$ , the sum exists. $\"\"$

$\"\"$ (Substitute $\"\"$ )

$\"\"$ (Product of two same signs is positive)

$\"\"$ (Add denominator: 1 + 0.6 = 1.6)

= 7.5 (Divide: $\"\"$ ) $\"\"$

The sum of the infinite geometric series is 7.5.
