That does not matter for my result. But obviously we go on with multi-digit natural numbers.
You should know that a simpler sequence replacing even and odd numbers by 0 and 1, repsectively, shows the same result. > > As it stands, your sequence is far too ambiguous to have any defineable > or determinable limit.
No. Every mathematician can determine the limit - not you, of course. > > > > > > No; it has no limit. > > > It has an improper limit in analysis, namely oo.

Sets of numbers are sets, whether or not they appear in my sequence of real numbers. There is no redifinition necessary.

Only if blind men try to read it. But I assume that Seymour J. Shmuel is not blind. So wait what he will have to say.
