Find analytically the solution of this difference equation with the given initial values:

Without computing the solution recursively, predict whether such a computation would be stable.

(Note: A numerical process is unstable if small errors made at one stage of the process are magnified in subsequent stages and seriously degrade the accuracy of the overall calculation.)
