<h3 class="section">85.1 Introduction to solve_rec</h3>
<p><code>solve_rec</code> is a package for solving linear recurrences with polynomial
coefficients.
</p>
<p>A demo is available with <code>demo("solve_rec");</code>.
</p>
<p>Example:
</p>
<div class="example">
<pre class="example">(%i1) load("solve_rec")$
</pre><pre class="example">(%i2) solve_rec((n+4)*s[n+2] + s[n+1] - (n+1)*s[n], s[n]);
n
%k (2 n + 3) (- 1) %k
1 2
(%o2) s = -------------------- + ---------------
n (n + 1) (n + 2) (n + 1) (n + 2)
