No, but you seem to have lost a bit of mathematical self control. I
try to get you back to sense.

Two sets can be unioned.
n sets can be unioned.
aleph_0 sets can be unioned.

Whether or not they belong to a sequence does not matter. Otherwise
the axioms should indicate that unioning sets that belong to a
sequence is prohibited.

you should be careful what you post as it could get you thrown out of school
+ math.

Your posting uses language that is not clear, perhaps intentionally, such as
the mixing of sequences and sets.
