Index entries for linear recurrences with constant coefficients, signature (62, 1).

FORMULA

a(n) = F(n, 62), the n-th Fibonacci polynomial evaluated at x=62. - T. D. Noe, Jan 19 2006

From Philippe Deléham, Nov 23 2008: (Start)

a(n) = 62*a(n-1) + a(n-2), n>1; a(0)=1, a(1)=62.

G.f.: 1/(1 - 62*x - x^2). (End)

MATHEMATICA

a=0; lst={}; s=0; Do[a=s-(a-1); AppendTo[lst, a]; s+=a*62, {n, 3*4!}]; lst (* Vladimir Joseph Stephan Orlovsky, Nov 03 2009 *)

Denominator[Convergents[Sqrt[962], 20]] (* Harvey P. Dale, Jun 15 2013 *)
