重新列举练习

我想重新编号下面的练习，将数字 1. 改为 9.，将数字 2. 改为 12.，将数字 3. 改为 15。我该如何进行？

\documentclass{article}

您可以创建自己的ManualExercise环境：

在此处输入图片描述

\documentclass{article}

\usepackage[lastexercise,answerdelayed]{exercise}
\renewcommand{\ExerciseName}{Exercises}
\renewcommand{\ExerciseHeader}{Exercises}

% Partial code taken from http://mirrors.ctan.org/macros/latex/contrib/exercise/exercise.dtx
\newenvironment{ManualExercise}
  {\begin{list}{}{\leftmargin \QuestionIndent
    \partopsep0pt \parsep\parskip \topsep\QuestionBefore
    \itemsep\QuestionBefore \labelwidth2em
    \labelsep.33em
    \usecounter{Question}}}
  {\end{list}}

\begin{document}

\begin{Exercise}
  \Question Lorem ipsum \ldots
  \Question Lorem ipsum \ldots
  \Question Lorem ipsum \ldots
\end{Exercise}

\begin{Exercise}
  \begin{ManualExercise}
    \item[9.~] Lorem ipsum \ldots
    \item[12.~] Lorem ipsum \ldots
    \item[15.~] Lorem ipsum \ldots
  \end{ManualExercise}
\end{Exercise}

\end{document}

原因Exercise在于exercise设置常规列表，但检查它是列表中的第一个\Question还是后续的\Question。基于此条件，创建自己的列表比更新列表以满足您的要求要容易得多。

列表参数与环境的参数相同Exercise，取自exercise.dtx。
