What is a Geometric Series?
A sequence of numbers such that the consecutive term is increasing or decreasing by a fixed ratio is called a geometric series.
The summation of the series is obtained by the expression k²-1
For [tex]\sum_{1\to 3} k = k^2 -3[/tex]
By adding the terms of the series
The terms of the series from 1 to 3 is -2, 1, 6
On adding the terms
=> -2 + 1 +6
= 5
