I just tagged a question iterated-functions, for a question concerning the limit of the sequence $x_{n+1} = \sqrt{3x_n}$ for various $x_0$. I was surprised that we don't seem to have a tag for this already. Did I miss something?

I'm not sure this new tag is a good idea, or that if it is a good idea, that it has the right name.

perhaps what I meant was recurrence

or recurrence-relation; we don't seem to have either of those, however.

@5pm That sounds to me like a good idea.

@5pm I agree, good idea.

Perhaps we can ask some of the mods to do this... (Or just create the tag, suggest the synonym and wait until it is upvoted.)
