Both of which, while true, do not in any way support WM's delusions or comradict the actual infiniteness of certain sets like the set of al;l natural numbers.
Note that, in general, the limit, if it exists, of a sequence or series need not be a member of that sequence or series, not even in Wolkenmuekenheim.
For example the sequence of all FISONs (finite initials sets of naturals), taken in order of increasing size, has a limitset which is not a FISON but is the union of all FISONs or, equivalently, of any infinite set of FISONs.
At least everywhere outside of Wolkenmuekenheim. -- --
