## Abstract

From the Rodrigues representation of polynomial eigenfunctions of a second order linear hypergeometric-type differential (difference or *q*-difference) operator, complementary polynomials (see, for example, [19]) for classical orthogonal polynomials are constructed using a straightforward method. Thus a generating function in a closed form is obtained.
For the complementary polynomials we present a second order linear hypergeometric-type differential (difference or *q*-difference) operator, a three-term recursion and Rodrigues formulas which extend the results obtained in [19] for the standard derivative operator.
