**SERIESSUM (x,n,m,coefficients)**

- is the power series value.
- is the initial power value.
- is the step value to increase the n value for each term.
- is the set of coefficients by which each successive power of x is multiplied.
- SERIESSUM(), returns the sum of a power series based on the formula.

## Description

- This function gives the value of the seriessum of the given set of values.
- Seriessum is defined by the following formula : .
- Here is the power-series value, is the starting power value, is the increasing value of a power and is the set of coefficients.
- According to the number of coefficients, the number of terms of the power series also get varies.
- For example there 5 values in coefficients, then 5 terms will be there in power series.

This function will give the result as error when any one of the argument is non-numeric.

## Examples

- =SERIESSUM(3,2,2,[1,2,3,4,5,6]) = 3512493
- =SERIESSUM(1,0,4,[1,2,3]) = 6
- =SERIESSUM(2,1,5,[2,4,6,8]) = 536836
- =SERIESSUM(0,2,4,[1,2,3,4,5]) = 0
- =SERIESSUM(1,0,3,[1,2,3,4,5]) = 15
- =SERIESSUM(1,1,5,[1]) = 1
