Recurrence relations for connection coefficients between Q-orthogonal polynomials of discrete variables in the non-uniform lattice x(s)=q(2s)

We obtain the structure relations for q-orthogonal polynomials in the exponential lattice q(2s) and from these we construct the recurrence relation for the connection coefficients between two families of polynomials belonging to the classical class of discrete q-orthogonal polynomials. An explicit example is also given.
