【Abstract】 In this paper, a parameter method for solving diophantine equation [Kx (x+1)=Dy (y+1)(y+2)(y+3),(x,y∈Z)] is given. [K=4D] and [K≠4D] are discussed respectively, and the parametric solution formula of the corresponding diophantine equation is obtained. [K,D] are coprime integers and [KD>0].
