<h2>
Given that</h2>
The formula for the geometric series is expressed as;
<h3>We have to determine</h3>
What is the value of r of the geometric series?
<h3>According to the question</h3>
The formula for the geometric series is expressed as;
<h3>The nth term of a geometric progression is expressed as;</h3>
Where a is the first term and r is the common ratio of the sequence.
In comparison both the terms;
Hence, the value of r of the geometric series is 0.8.
