OEIS Sequences

G.f. A(x) defined by: A(x)³ consists entirely of integer coefficients between 1 and 3 (A083953); A(x) is the unique power series solution with A(0)=1. A84203

The 5x + 1 sequence beginning at 7. A28389

Triangle read by rows: T(n,k) is the number of weighted lattice paths in B(n) having k valleys. The members of B(n) are paths of weight n that start at (0,0), end on but never go below the horizontal axis, and whose steps are of the following four kinds: an (1,0)-step with weight 1, an (1,0)-step with weight 2, a (1,1)-step with weight 2, and a (1,-1)-step with weight 1. The weight of a path is the sum of the weights of its steps. A valley is a (1,-1)-step followed by a (1,1)-step. A182900
