When I'm using sequences in an article, I always type things like (x_n)_n
and (x_n^k)_n
. However, that doesn't display the subscript after the brackets very nicely. I know that I can fix this by using \left(
and \right)
, but I forget about them most of the time (causing a lot of frustrations when I discover it after I printed my document).
\documentclass[]{article}
\begin{document}
These sequences aren't displayed perfectly:
$$(x_n)_n \qquad (x_n^k)_n.$$
These ones look okay:
$$\left(x_n\right)_n \qquad \left(x_n^k\right)_n.$$
\end{document}
Maybe it's because I find the use of \left(
and \right)
a bit too time-consuming. I'm therefore wondering whether there's a clean way to achieve the same thing somewhat faster.
(I'd find it no offence if you simply answer that I shouldn't be that forgetful... ;) )
(x_n^k)^{}_n
in the first set and you'll be OK.$$
, though.
