Learning what $\{a_{k}\}^{n}_{0}$ means

Question

Somewhere I saw the notation $\{a_{k}\}^{n}_{0}$ used. I believe it was used for a summation, but I'm not sure. What does this actually mean and can also use it to describe the set $\{a_0,a_1,...,a_n\}$?

Yes, it typically just means ${a_0, a_1,...,a_n}$. – MathematicsStudent1122 Oct 31 '19 at 02:29 — MathematicsStudent1122, Oct 31 '19 at 02:29

That is a short way to denote the sequence of elements $$a_k,$$ as $k$ runs over some index set. Here, $k$ runs from $0$ to $n.$
