Additive sequences

[franktaw at netscape.net]

I'm not sure it's a good name either.  My own preference
would be "log multiplicative", since when you exponentiate
such a sequence you get a multiplicative sequence.

But "additive" is, as stated, already in use in the database.
Barring a finding of the form "there's a lot of literature on
these, and they're called X", it isn't going to change.

I'm not sure if this is a good name, as it implies having
something to do with 'additive number theory' which is
way off here.

(I'm not against, just count it as abstention)
