GEOMETRICSERIES (Start,CommonRatio,Numbers,OnlyNth)

Description

This function returns the value of the Geometric Series.
In $GEOMETRICSERIES(Start,CommonRatio,Numbers,OnlyNth)$ , $Start$ is the Initial number of the geometric series.
$CommonRatio$ is the difference between the numbers.
$Numbers$ is the number of the terms to display.
$OnlyNth$ means it will show the final term of the series.
Geometric series means a series of numbers or quantities in geometric progression.
So it is the ratio of successive terms in the series is constant.
Geometric series using only two terms r and a.
The term r is the common ratio,and a is the first term of the series.
The sum of the first n terms of a geometric series is:

$a+ar+ar^{2}+ar^{3}+....$ with $r={\frac {1}{2}}$ and $a={\frac {1}{2}}$

This function will return the result as Error when the parameters are non-numeric.
