| Abstract: | In this paper, we consider the logistic equation.Xn+1 = Xnern(a-bxn-k-x2n-k, n = 0, 1, …where {rn} is a sequence of nonnegative real number . k≥0 a integer. a＞O, b ＞O. we establish some sufficient conditions for an axbtw solution {xn} Satisfying the intial condition of the form.Xi=aj≥0 j= -k, -k+ 1,…, -1, x0=a0＞0to Converge to the positive equilibribbm N. as n→∝. |
