# Recurrence relation

recurrence formula

A relation of the form

permitting one to compute all members of the sequence if its first members are given. Examples of recurrence relations are: 1) , a geometric progression; 2) , an arithmetic progression; 3) , the sequence of Fibonacci numbers.

In the case where the recurrence relation is linear (see Recursive sequence) the problem of describing the set of all sequences that satisfy a given recurrence relation has an analogy with solving an ordinary homogeneous linear differential equation with constant coefficients.
