%N Numerators of continued fraction convergents to sqrt(29).
%C From _Johannes W. Meijer_, Jun 12 2010: (Start)
%C The terms of this sequence can be constructed with the terms of sequence A087130.
%C For the terms of the periodical sequence of the continued fraction for sqrt(29) see A010128. We observe that its period is five. The decimal expansion of sqrt(29) is A010484. (End)
