How to solve recurrences

WebApr 6, 2024 · In this paper, we take a step towards solving these recurrences. Specifically, we consider what we call conditional linear recurrences and show that given such a recurrence and an initial value, if the index sequence generated by the recurrence on the initial value is what we call ultimately periodic, then it has a closed-form solution.
