Show me the steps of determine blue and inf is here please step by step and i want every details

[(a1 + a3 + a5) - (a2 + a4)] + ô
P =

and
[(a1 + az + a5) – (a2 + a4)] – 6
Q =
(4.22)
2 [(B1 + B3 + B5) + A (B2 + B4)]
where
8 = V[(a1 + a3 + a5) – (a2 + a4)]² – n,
and
4[(a1 + a3 + a5) – (a2 + a4)] [(B1 + B3 + B5) (a2 + a4) + A (B2 + B4) (aj + az + a5)]
[((32 + B4) – (B1 + B3 + B5)) (A+ 1)]
Now, let us prove that P and Q are positive solutions of prime period two of
Eq.(1.1). To this end, we assume that y-5 = P, y-4 = Q, y-3 = P, y-2 =
Q, y-1 = P, yo = Q. Now, we are going to show that yı = P and y2 = Q.
From Eq.(1.1) we deduce that
