Let U(P,Q) denote the Lucas sequence satisfying the recursion relation Un+2 = PUn+1 − QUn, where U0 = 0, U1 = 1, and P and Q are integers. Let z(n), called the rank of appearance of n in U(P,Q), denote the least positive integer m such that Um 0 (mod n). We find all fixed points n for the rank of appearance such that z(n) = n. We also show that z(n) 2n when z(n) exists. This paper improves results considered by Diego Marques regarding the Fibonacci sequence.
