COMMENT

The twice the ratio approaches 1/alpha: b = Table[2*N[a[[n + 1]]/a[[n]]], {n, 2, 200}] The characteristic polynomial is a Pisot : 9389 + 4691* x - x^3 NSolve[Det[M - IdentityMatrix[3]*x] == 0, x] {{x -> -67.4673}, {x -> -2.00321}, {x -> 69.4705}}

FORMULA

M = {{0, 1, 0}, {0, 0, 1}, {9389, 4691, 0}} w[n]=M.w[n-1] a(n) = w[n][[1]]

MATHEMATICA

M = {{0, 1, 0}, {0, 0, 1}, {9389, 4691, 0}} w[0] = {0, 1, 1} w[n_] := w[n] = M.w[n - 1] a = Flatten[Table[w[n][[1]], {n, 0, 25}]]
