I am figthing with a series which doesn't look very complicated but I
can't sort it out.
Here it is:
a[0,0] = 1;
a[m,n] = (n+1)a[m-1,n+1] - a[m-1,n-1]
It's not a series, or even a sequence, because it has two indices.
And you haven't given us enough information to specify it completely.
It turns out that if m+n is even, a[m,n] = 0.
That contradicts your statement a[0,0] = 1.
