Summing series using recurrence relations
Published 15 Jan 2026 in math.GM | (2601.10777v1)
Abstract: Power series in which the summand satisfies a linear recurrence relation with polynomial coefficients are shown to be the solution of a linear differential or algebraic equation. Solving the associated differential or algebraic equation yields a closed form for the series. This method is used to sum several series and to solve two {\it American Mathematical Monthly} problems.
