A, P, R, X, S and Z are sitting in a row. S and Z are in the centre. A and P are at the ends. R is sitting to the left of A. Who is to the right of P?

X sits immediately to the right of P.

A and P take the two ends; R is just left of A, so A is at the right end and R next to it.

That fixes P at the left end, R at position 5 and A at position 6.

S and Z occupy the two centre seats, positions 3 and 4.

The only seat left, position 2, next to P, goes to X.

So the person to the right of P is X.
