SERIESSUM

Calculates the sum of a power series based on the formula: x^n + x^(n+m) + x^(n+2m)

Parameter List

Syntax
SERIESSUM(xnmcoefficients)
x

The input value for the power series. For example: 2, 0.5, A1.

n

The initial power to which x is raised. For example: 0, 1, 2.

m

The step by which to increase the power for each term. For example: 1, 2, 3.

coefficients

An array of coefficients for each term in the series. For example: {1,2,3}, A1:A5, or a range of values.

More details

SERIESSUM calculates the sum of a power series: coefficient₁×x^n + coefficient₂×x^(n+m) + coefficient₃×x^(n+2m) + ... This is useful for mathematical series calculations, Taylor series approximations, and polynomial evaluations. The coefficients array determines how many terms are included in the series.
