I think they intend that a(n) is defined for n being an integer (or
maybe just the Natural Numbers, since it isn't defined for values below 1)

The two provided definitions provide the recursive definition for even
and odd values.

I am not sure what 'fractal' property this sequence has that he wants to
display.
