Abstract: With the help of the formula for the general solution of a difference equation with constant coefficients, it is shown that the set of solutions to this equation contains classical solutions of the type $k^m\lambda^k$. We present necessary and sufficient conditions on the coefficients of the equation and the initial parameters under which such solutions are obtained.

Keywords: difference equation, conditions on the coefficients of an equation.
