%N Numerators of the ordinary convergents of continued fraction [2/1, 3/2, 4/3, 5/4,...].

%C Suppose that x(n) is a sequence of positive real numbers with divergent sum. By the Seidel Convergence Theorem, the continued fraction [x(1),x(2),x(3),...] converges.

%e [2/1, 3/2, 4/3, 5/4, ...] = 2.492459746021286... The first 5 ordinary convergents are 2, 5/2, 162/65, 167/67, 329/132.

%t z = 500; t = Table[(n+1)/n, {n, z}]
