More generally the main diagonal of the array defined by T(0,j)=j+1 j>=0, T(i,0)=i+1 i>=0, T(i,j)=T(i-1,j-1)+T(i-1,j)+ A, is given by T(n,n)=2^(n-1)*(n+2A+2)-A - Benoit Cloitre, Jun 17 2003

Formula

Main diagonal of the array defined by T(0, j)=j+1 j>=0, T(i, 0)=i+1 i>=0, T(i, j)=T(i-1, j-1)+T(i-1, j)+ 6; a(n)=2^(n-1)*(n+14)-6 - Benoit Cloitre, Jun 17 2003
