How to find a and b? (pascal's triangle)

The two 5005s tell us we're in the middle of Pascal's triangle, which has bilateral symmetry.

So we can add the a and b labels to two other points by the symmetry as shown.

The two equations we can write are then

5005 + a = b

a + a = 12870

a = 12870/2 = 6435

b = 5005 + 6535 = 11540

a=6435, b=11540
