The convergence of solution to this equation is investigated by introducing a new sequence which extends and includes corresponding results obtained in the references Li in J Math Anal Appl 312 103-111 2005 Berenhaut et al. Appl. Math. Lett. 20 54-58 2007 Papaschinopoulos and Schinas J Math Anal Appl 294 614-620 2004 to a large extent. In addition some propositions for generalized equations are reported. Keywords Nonlinear Difference equation Global stability Positive solution 1 Introduction Our aim in this paper is to study the dynamical behavior of the following equation xn-k xn-m xn-1 Xn ------------------- - n 0 1 2 . xn-kxn-m xn-mxn-1 1 where the initial data x-1 x-i 1 . x-1 e R and 1 k m l. The study of properties of similar difference equations has been an area of intense interest in recent years 1-3 . There have been a lot of work concerning the behavior of the solution. In particular Qinar 4 studied the properties of positive solution to xn-1 xn 1 1 xnxn-1 n 0 1 . Yang et al. 5 investigated the qualitative behavior of the recursive sequence axn-1 bxn-2 xn 1 J c dxn-1xn-2 n 0 1 . Springer Li et al. 6 studied the global asymptotic of the following nonlinear difference equation xn-1xn-2xn-3 xn-1 xn-2 xn-3 a xn 1 --------------. . .---L-- 3-------- n 0 1 . 1 xn-1xn-2 xn-1xn-3 xn-2xn-3 a with a 0.
