A Novel Summation Identity by Using Delannoy Triangle

Abstract

In this paper, we study the balancing and co-balancing problems for the coefficients located along the direction $(1,-1)$ of  the Delannoy triangle. Motivated by our search for the solutions of balancing problem, we give a novel identity on the Delannoy triangle.
