This paper is concerned with the existence of positive solution to the discrete three-point boundary value problem


where , and f is allowed to change sign. By constructing available operators, we shall apply the method of lower solution and the method of topology degree to obtain positive solution of the above problem for on a suitable interval. The associated Greenís function is first given.
