  We prove that the N-colored Jones polynomial for the torus knot T_{s,t}
satisfies the second order difference equation, which reduces to the first
order difference equation for a case of T_{2,2m+1}. We show that the
A-polynomial of the torus knot can be derived from this difference equation.
Also constructed is a q-hypergeometric type expression of the colored Jones
polynomial for T_{2,2m+1}.
