%N 2*A065941 - A049310.
%C Row sums = the Lucas numbers, A000032, starting (1, 3, 4, 7, 11, ...). Generally, N*A065941 - (N-1)*A049310 = triangles with row sums = Fibonacci-like sequences starting (1, (N+1), (N+1+1), ...). With N = 2, row sums of the triangle A131774 = (1, 3, 4, 7, ...).
%F 2*A065941 - A049310 as infinite lower triangular matrices.
%e First few rows of the triangle:
%e 1;
%e 2, 1;
%e 1, 2, 1;
%e 2, 0, 4, 1;
%e 1, 2, 3, 4, 1;
