numbers such that k <1< o. Note that the special cases

Theorem 12.If k, o are even and 1 is odd positive integers,
then Eq. (1) has prime period two solution if the condition
(3e- d) (1-C)< (e+d)(A+B+D),
(39)
is valid, provided C<1 and e (1 –C)-d(A+B+D) >
0.
Proof.If k, o are even and I is odd positive integers, then
Xn = Xn-k = Xn-o and xn+1 = Xn–1. It follows from Eq.(1)
that
bQ
P=(A+B+D) Q+CP –
(40)
(е Р- dQ)'
and
bP
Q= (A+B+D) P+CQ -
(41)
(e Q- dP)
Consequently, we get
P+Q=
(42)
[e (1–C)-d (A+B+D)]’
where e (1 – C) - d (A+B+D) > 0,
eb? (1– C)
(e+d) [(1– C)+ K4] [e (1 – C )– d K4]²
PQ=
(43)
where Ką = (A+B+D), provided C< 1. Substituting
(42) and (43) into (28), we get the condition (39). Thus,
the proof is now completed.O
