%N Numerators of convergents of selfgenerating continued fraction with first term 2.
%C For x > 0, define c(x,0) = x and c(x,n) = [c(x,0), ..., c(x,n1)]. We call f(x) the selfgenerating continued fraction with first term x. See A229779.
%H Vincenzo Librandi, <a href="/A229918/b229918.txt">Table of n, a(n) for n = 0..11</a>
%e The first four convergents are 2/1, 5/2, 29/12, 961/396.
%t z = 10; c[x_, 0] := x; c[x_, n_] := c[x, n] = FromContinuedFraction[Table[c[x, k], {k, 0, n  1}]]; x = 2; t = Table[c[x, k], {k, 1, z}];
