SUMMARY

The subsets of R that are both sequentially compact and connected are precisely the closed and bounded intervals. In the context of real numbers, connected subsets include the empty set, individual points, and intervals. The discussion confirms that the term 'continuous' is unnecessary when describing these intervals, as the definition inherently implies 'without holes'. The user expresses confidence in this conclusion and seeks assistance with editing thread titles.

Homework Statement



Which subset of R are both sequentially compact and connected?

Homework Equations





The Attempt at a Solution


The connected subsets of R are the empty set, points, and intervals.
The subsets of R that are compact are closed and bounded.

Thus, the subsets of R that are both sequentially compact and connected are closed, bounded continuous intervals. Is this correct?

I'm convinced. But I don't think you need to say an interval is 'continuous'. If you mean 'without holes' isn't that automatic?
 
Yes, I see what you mean. Thank you.

Does anyone know how to close or edit the words "SOLVED" in threads?
