The objective of this article is to investigate some
qualitative behavior of the solutions of the nonlinear
difference equation
bxn-k
Xn+1 = Axn+ Bx–k+Cxn-1+ Dxn-o+
dxn-k– exŋ-
n= 0,1,2,.....
(1)
where the coefficients A, B, C, D, b, d, e E (0,0), while
k, 1 and o are positive integers. The initial conditions
X_g,..., X_1,.., X_k, ….., X_1, X are arbitrary positive real
numbers such that k <1< 0. Note that the special cases
of Eq.(1) have been studied in [1] when B=C= D=0,
and k= 0,1= 1, b is replaced by – b and in [27] when
B=C= D=0, and k= 0, b is replaced by
[33] when B = C = D = 0, 1= 0 and in [32] when
A=C= D=0, 1=0, b is replaced by – b.

Theorem 9.If k is even and 1,0 are odd positive integers,
then Eq. (1) has prime period two solution if the condition
(1— (С+D)) (Зе— d) < (е+d) (А+ В),
(20)
is
valid,
provided
(C+D)

and
е (1— (С+D))—d (А+ B) > 0.
Proof.If k is even and 1, 0 are odd positive integers, then
Xn+1 = Xn–1= Xn=o. It follows from Eq.(1)
