WebMar 24, 2024 · A recurrence equation (also called a difference equation) is the discrete analog of a differential equation. A difference equation involves an integer function f(n) in a form like f(n)-f(n-1)=g(n), (1) where g is some integer function. The above equation is the discrete analog of the first-order ordinary differential equation f^'(x)=g(x). (2) Examples of …
