A118550 Seqs increasing fast then slow then fast then...

[Graeme McRae]

Leroy,
These sequences are very interesting.  I used your idea (and I credit it by 
referencing the sequence in the database) in a web page, 
http://mcraefamily.com/MathHelp/GeometryFractalSequence.htm . I would be 
amazed if anyone discovers a closed form for this sequence, since it is so 
apparently chaotic.
