SERIESSUM

Evaluates a power series.

Syntax:

SERIESSUM( x:Number, n:Number, m:Number, coefficients:Range or Array )

Returns the sum of the given power series for x.

n is the initial power to which x is raised, this being multiplied by the first value from the coefficients range of cells (or array) of numeric values. For each subsequent coefficient, m is added to the power.

Formula:

SERIESSUM = a1xn + a2x(n + m) + a3x(n + 2⋅m) + … + aNx(n + (N-1)⋅m)
