*This function gives the value of the seriessum of the given set of values.  

*This function gives the value of the seriessum of the given set of values.  

*Seriessum is defined by the following formula<math>:SERIESSUM(x,n,m,a)= a_1x^n + a_2x^{(n+m)} + a_3x^{(n+2m)} + … + a_jx^{(n+(j-1)m)}  </math>.  

*Seriessum is defined by the following formula<math>:SERIESSUM(x,n,m,a)= a_1x^n + a_2x^{(n+m)} + a_3x^{(n+2m)} + … + a_jx^{(n+(j-1)m)}  </math>.  

*Here x is the powerseries value, n is the starting power value,m is the increasing value of a power and a is the set of coefficients. According to the number of coefficients , the number of terms of the power series also get varies.  

*Here <math>x</math> is the powerseries value, <math>n</math> is the starting power value, <math>m</math> is the increasing value of a power and <math>a</math> 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.
