As is well-known, the ratio of adjacent Fibonacci numbers tends to phi = (1 +sqrt(5))/2, and the ratio of adjacent Tribonacci numbers (where each term isthe sum of the three preceding numbers) tends to the real root eta of X^3 - X^2- X - 1 = 0. Letting alpha(n) denote the corresponding ratio for thegeneralized Fibonacci numbers, where each term is the sum of the n preceding,we obtain rapidly converging series for alpha(n), 1/alpha(n), and1/(2-alpha(n)).
