I am not familiar with a convention that includes the
limit as part of the sequence. That sounds like a bad idea
to me, not least because we can't assume that a particular
sequence has a limit.
In this discussion, no matter what you may be familiar with,
it's important to keep clear which we're talking about at
any point: the sequence or the limit of the sequence.
Anyway, what netzwelter wrote out is what I asked for,
that sequence defined without '...' My hope is that he
does not take your advice.
