Abstract
Let be an integral linear recurrence, be an integer-valued polynomial splitting over the rationals, and be a positive integer. Also, let be the set of all natural numbers such that . We prove that has a natural density. Moreover, assuming is non-degenerate and has no fixed divisors, we show that if and only if is finite.
