Dear SeqFans,
There is the following comment in the sequence of evil numbers A001969:
a(n)-A001285(n) = 2n-1 has been verified for n=0,1,2,...,400 - John W.
Layman (layman(AT)math.vt.edu)
The proof of this comment follows from the next comment:
"First differences give A036585. Observed by Franklin T. Adams-Watters,
proved by Max Alekseyev, Aug 30 2006. This is equivalent to a(n) = 2*n
+ A010060(n). Proof: If the number of bits in n is odd then the last
bit of a(n) is 1, and if the number of bits in n is even then the last
bit of a(n) is 0. Hence the sequence of last bits is A010060. Therefore
a(n) = 2*n + A010060(n)."
and from the fact that A001285 is A010060 + 1.
I do not know how to suggest changes inside other peoples comments.
Tanya
