I'm often writing equations with quantifiers like these:

```
\begin{equation*}
x_i \quad \forall i = 1, \dotsc, n
\end{equation*}
```

I've read this answer, but I'm not sure if my case is an example for a situation where one uses EM quad.

So my first question is, would you put a `\quad`

space at that position?

The second question is, would you separate the first part from the quantifier with a comma like:

```
\begin{equation*}
x_i \quad , \forall i = 1, \dotsc, n
\end{equation*}
```

## Best Answer

Don't put a space before the comma, Also I would not use

`\forall`

with an informal iterator displayed as dots.Assuming

`x_i`

is some boolean valued expression indexed by`i`

then eitheror more formally
