We introduce a necessary and sufficient criterion for determining the existence and the values of ratio limits of complex sequences generated by arbitrary linear recurrences.
We study ratio limits of the consecutive terms of weighted $n$-generalized Fibonacci sequences generated from arbitrary complex initial conditions by linear recurrences with arbitrary complex weights. We prove that if the characteristic polynomial of such a linear recurrence is asymptotically simple, then the ratio limit exists for any sequence generated from arbitrary nontrivial initial conditions and it is equal to the unique zero of the characteristic polynomial.
We study generalizations of the sequence of the n-anacci constants that consist of the ratio limits generated by linear recurrences of an arbitrary order n with equal positive weights p. We derive the analytic representation of these ratio limits and prove that, for a fixed p, the ratio limits form a strictly increasing sequence converging to p+1. We also construct uniform geometric representations of the sequence of the n-anacci constants and generalizations thereof by using dilations of compact convex sets with varying dimensions n. We show that, if the collections of the sets consist of n-balls, n-cubes, n-cones, n-pyramids, etc., then the representations of the generalized n-anacci constants have clear geometric interpretations.
