## Works
```
\\[
a_{n} = b_{n}
\\]
```
\\[
a_{n} = b_{n}
\\]
## Doesn't work
```
\\[
\bar{a}_{n} = b_{n}
\\]
```
\\[
\bar{a}_{n} = b_{n}
\\]
## Workaround
```
\\[
\bar{a}\_{n} = b_{n}
\\]
```
\\[
\bar{a}\_{n} = b_{n}
\\]
Notes
- Sorry if this is a duplicate. I see that the MathJax support is in flux right now (though I couldn't find this particular issue).
- The workaround will not work in LaTeX.
$a\_{n}$
forces a literal underscore. - You can reproduce the error with just
{a}_{n} = b_{n}
(I used\bar{a}_{n} = b_{n}
because it's something someone might actually want to write).
