Introduction to Recurrence Relation Solutions

Recurrence relation solutions (漸化式の解法) refer to methods or algorithms used to find the explicit formula of a sequence defined by a recurrence relation. A recurrence relation is an equation that recursively defines a sequence, where each term is a function of its preceding terms. The primary design purpose of solving recurrence relations is to convert recursive sequences into direct formulas that allow for the calculation of any term in the sequence without needing to compute all previous terms. For example, the Fibonacci sequence, defined by the recurrence relation F(n) = F(n-1) + F(n-2) with F(1) = F(2) = 1, is a classic scenario illustrating the application of these methods. Solving it provides a direct formula to find any Fibonacci number. Powered by ChatGPT-4o
