Notation for a sequence of points












1














I want to say a sequence of points in $mathbb{R}^3$. Which of the following ways of writing is correct?
begin{equation}
{p_n in mathbb{R}^3}_{n=1}^{infty}
end{equation}

or
begin{equation}
{p_n }_{n=1}^{infty} in mathbb{R}^3
end{equation}

    ${p_n} subset mathbb R^{3}$.

  • "Let $(p_n)$ be a sequence of points in $mathbb{R}^3$" is quite clear. Why use symbols when words are better?

Pedantically, a sequence $(p_n)$ of points in $mathbb{R}^3$ is a function $p: mathbb N to mathbb{R}^3$, but almost no one writes a sequence like this.



A notation like ${p_n }_{n=1}^{infty}$ suggests the set that is the image of the sequence, not the sequence itself.



Why use symbols when words are better? The sentence below is quite clear.




Let $(p_n)$ be a sequence of points in $mathbb{R}^3$.
