RSolveValue

RSolveValue[eqn,expr,n] gives the value of expr determined by a symbolic solution to the ordinary difference equation eqn with independent variable n. 

RSolveValue[{eqn1,eqn2,…},expr,…] uses a symbolic solution for a list of difference equations. 

RSolveValue[eqn,expr,{n1,n2,…}] uses a solution for the partial recurrence equation eqn.
