%N Decimal expansion of the lower limit of the convergents of the continued fraction [1/2, 1/4, 1/8, ... ].
%C Since sum{2^(-k), k=1,2,...} converges, the convergents of [1/2, 1/4, 1/8, ... ] diverge, by the Seidel Convergence Theorem. However, the odd-numbered convergents converge, as do the even-numbered convergents. In the Example section, these limits are denoted by u and v.
%e u = 0.659898678... = [0, 1, 1, 1, 15, 1, 3, 127, 1, 7, 1023, 1,...];
%e v = 3.507873955... = [3, 1, 1, 31, 3, 1, 255, 7, 1, 2047, 15, ...].
%e In both cases, every term of the continued fraction has the form 2^m - 1.
%t $MaxExtraPrecision = Infinity; z = 500; t = Table[2^(-n), {n, 1, z}]; u = N[Convergents[t][[z - 1]], 120]; v = N[Convergents[t][[z]], 120];
