WebAug 17, 2024 · The process of determining a closed form expression for the terms of a sequence from its recurrence relation is called solving the relation. There is no single technique or algorithm that can be used to solve all recurrence relations. In fact, some … WebWhen you write a recurrence relation you must write two equations: one for the general case and one for the base case. These correspond to the recursive function to which the recurrence applies. The base case is often an O (1) operation, though it can be otherwise.
