Vincenzo Librandi, Table of n, a(n) for n = 0..5000
Index entries for linear recurrences with constant coefficients, signature (2,-1).
FORMULA
a(n) = 2*a(n-1) - a(n-2); a(0)=14, a(1)=105. - Harvey P. Dale, Feb 25 2015
From Elmo R. Oliveira, Apr 04 2024: (Start)
G.f.: 7*(2+11*x)/(x-1)^2.
E.g.f.: 7*exp(x)*(2 + 13*x).
a(n) = 7*A153080(n). (End)
