How do Mathematicians pronounce the ellipsis? (...) for instance:(adsbygoogle = window.adsbygoogle || []).push({});

1 + 2 + 3 + ... + a_{n}

"One plus two plus three plus dot dot dot plus a sub n"?

I'm using a digital tape recorder to better understand text, and I don't want to pronounce this incorrectly.

Also: do mathematicians say "the arc tangent of one" or "the inverse tangent of one"?
