Abstract

The sequence a(1), a(2), a(3), . . . , labelled A088431 in the Online Encyclopedia of Integer Sequences, is defined by: a(n) is half of the (n + 1)th component, that is, the (n + 2)th term, of the continued fraction expansion of {equation presented} Dimitri Hendriks has suggested that it is the sequence of run lengths of the paperfolding sequence, A014577. This paper proves several results for this summed paperfolding sequence and confirms Hendriks's conjecture.
