FORMULA
From Mohammad K. Azarian, Dec 26 2008: (Start)
G.f.: 1/(1-x) + 1/(1-5*x) + 1/(1-7*x).
E.g.f.: e^x + e^(5*x)*e^(7*x). (End)
a(n) = 12*a(n-1) - 35*a(n-2) + 24 with a(0)=3, a(1)=13. - Vincenzo Librandi, Jul 21 2010
a(0)=3, a(1)=13, a(2)=75, a(n) = 13*a(n-1) - 47*a(n-2) + 35*a(n-3). - Harvey P. Dale, Apr 15 2015
