In this paper, we consider the k-th Riesz mean for the coefficients of the Rankin-Selberg L-function Lf × f(s) related to the Godement-Jacquet L-function with respect to SL(n,ℤ). We establish an asymptotic formula for the k-th Riesz mean with an improved range and a better error term. As a result, we get an asymptotic relation for the partial sum of the coefficients of Lf × f(s).
