sage: import sympy sage: sympy.rsolve?

gives :

```
Signature: sympy.rsolve(f, y, init=None)
Docstring:
Solve univariate recurrence with rational coefficients.
Given k-th order linear recurrence \operatorname{L} y = f, or
equivalently:
a_{k}(n) y(n+k) + a_{k-1}(n) y(n+k-1) + ... + a_{0}(n) y(n) =
f(n)
where a_{i}(n), for i=0, ..., k, are polynomials or rational
functions in n, and f is a hypergeometric function or a sum of a
fixed number of pairwise dissimilar hypergeometric terms in n,
finds all solutions or returns "None", if none were found.
