Giovanni Resta, Table of n, a(n) for n = 1..3000 (first 650 terms from Peter Kagey)
EXAMPLE
a(4) != 4 or else midpoint((4,4), (1,1)) = midpoint((2,2), (3,3)), thus
a(4) = 5.
a(6) != 6 or else midpoint((6,6), (3,3)) = midpoint((4,5), (5,4));
a(6) != 7 or else midpoint((6,7), (1,1)) = midpoint((3,3), (4,5)); thus
a(6) = 8.
