Properties

Appears in sequences

• Solution of the complementary equation a(n) = a(n-1) + a(n-2) + b(n-1) - b(n-2) + 1, where a(0) = 1, a(1) = 2, b(0) = 3, and (a(n)) and (b(n)) are increasing complementary sequences.at n=23A294562
• a(n) = Sum_{k=0..floor(n/2)} binomial(k+2,2) * binomial(k,3*(n-2*k)).at n=28A392255
