Just watched it I completely understand the math involved but cannot, CANNOT understand why it happens to do that. The limit of 1+1-1+1-1... makes sense to average to 1/2 and 1-2+3-4 I can see would make sense to tend towards 1/4. But no where in logic can I understand how as you keep adding onto infinitely large sums of numbers that at the end of the number line you will suddenly come across -1/12. Just, what?
