Please make a donation to keep the OEIS running. We are now in our 56th year. In the past year we added 10000 new sequences and reached almost 9000 citations (which often say "discovered thanks to the OEIS").

FORMULA

From Wesley Ivan Hurt, Oct 05 2020: (Start)

a(n) = 4*n^3 + 24*n^2 + 35*n.

a(n) = 4*a(n-1) - 6*a(n-2) + 4*a(n-3) - a(n-4).

G.f.: 3*x*(21-18*x+5*x^2)/(1-x)^4. (End)
