Formula

From Elmo R. Oliveira, Apr 16 2024: (Start)

G.f.: 60*x/(x-1)^2.

E.g.f.: 60*x*exp(x).

a(n) = 60*n = 2*a(n-1) - a(n-2) for n >= 2.

a(n) = 2*A249674(n) = 3*A008602(n) = 4*A008597(n) = 5*A008594(n) = 6*A008592(n) = 10*A008588(n) = 12*A008587(n) = 15*A008586(n) = 20*A008585(n) = 30*A005843(n) = 60*A001477(n) = A169827(n)/14 = A169825(n)/7. (End)
