Linear Homogeneous Recurrence Relation with Constant Coefficients

A linear homogeneous recurrence relation with constant coefficients is a recurrence relation of the form:

$a_n = c_1 a_{n-1} + c_2 a_{n-2} + \cdots + c_k a_{n-k}$

where $c_1, c_2, \ldots, c_k$ are constants and $k$ is the order of the recurrence relation.

To solve such a recurrence relation, we use the characteristic equation method:

Assume a solution of the form $a_n = r^n$
Substitute into the recurrence relation to get the characteristic equation
Solve for the roots $r$
The general solution depends on the nature of the roots (distinct, repeated, or complex)
