Vincenzo Librandi, Table of n, a(n) for n = 0..200
Index entries for linear recurrences with constant coefficients, signature (16,-60).
FORMULA
a(n) = 16*a(n-1) - 60*a(n-2) for n > 1; a(0) = 1, a(1) = 12.
G.f.: (1 - 4*x)/((1 - 6*x)*(1 - 10*x)).
E.g.f.: exp(6*x)*(3*exp(4*x) - 1)/2. - Stefano Spezia, Mar 21 2023
