# [Tex/LaTex] How to skip an \item in sub-enumerate level

#enumeratelistsnumbering

I would like to skip an \item in a sub-enumerate level. More specifically, I want the output to look something like:

1.
a)
b)
e)
f)
etc.

2.


However, when I use \addtocounter{enumi} (within the first \begin{enumerate} \end{enumerate} block obviously), it increases the outer counter and I get:

1.
a)
b)
c)
d)
etc. (no skips!)

3.


So I am looking for a way to specify which counter to increase. Greatly appreciate the help!

There's a counter for each level:

\documentclass{article}
\begin{document}
\begin{enumerate}
\item \mbox{}
\begin{enumerate}
\item

In the default document class(es), enumi controls the enumeration at level 1, enumii for level 2, enumiii for level 3 and enumiv for level 4.
