As Wolfgang says -- dunno why the 4 (my code below works for 3)
And I wonder whether you are making us do your homework.
Still heres something to start you off

def row(max,n): return range(2*n-1, max+n)
def tri(max): return [row(max,i) for i in range(1,max+1)]
 >>> tri(3)
[[1, 2, 3], [3, 4], [5]]
>>>
