do you need the abs() ? you are going to square the value later...

z = (x3 * x3) + (y3 * y3)
return math.sqrt(z)

you might want to check for m,n < 0.

And you do want to put some test code in here with "assert" statements.

if l == 1:
return m
if l == 2:
return n
return sum_series(l-2,m,n) + sum_series(l-1,m,n)
