Greubel, Table of n, a(n) for n = 0..985 Index entries for linear recurrences with constant coefficients, signature (16, -59). FORMULA a(n) = ((5+sqrt(5))*(8+sqrt(5))^n + (5-sqrt(5))*(8-sqrt(5))^n)/10. G.f.: (1-7*x)/(1-16*x+59*x^2). E.g.f.: (1/5)*exp(8*x)*(5*cosh(sqrt(5)*x) + sqrt(5)*sinh(sqrt(5)*x)). - G. C.
