 Jan 24 comment What is the integral $\int\limits_1^3\frac{e^{\frac{1}{x}}}{x^{2}}dx$? I should have followed through with the substitution. It was simpler than I thought.

The general solution must include all possible particular solutions. Since this is a linear relationship, the general solution is the sum of all linearly independent sequences that satisfy the relation. You will find that the order of the recursion relationship determines how many linearly independent sequences make up a the solution set.
