I believe that i'th is incorrect.  We use "nth" for n, although "ith"
looks funny to me.  However, I believe that, as long as the context is
clear (that we're talking about the variable "i"), I think that's the
correct term.  I'm pretty sure that i'th and i-th are things made-up by
people who just weren't sure what to do.
