write some other text here

% write another enumerated list here of the same type, but continuing with the numbering of the previous one.
begin{enumerate}[leftmargin=0.85cm, label=Aarabic*.]

begin{document}

  begin{enumerate}[leftmargin=0.85cm, label=Aarabic*.]
    item First item
    item Second item
  end{enumerate}
  If you don't mind having to re-specify everything:
  begin{enumerate}[leftmargin=0.85cm, label=Aarabic*., resume]
    item Third item
    item Fourth item
  end{enumerate}
  If you would prefer not to re-specify:
  begin{enumerate}[resume*]
    item Fifth item
    item Sixth item
  end{enumerate}
  What if you want to use first one enumeration:
  begin{enumerate}[leftmargin=0.85cm, label=Darabic*., series=denum]
    item First item
    item Second item
  end{enumerate}
  And then another:
  begin{enumerate}[leftmargin=0.85cm, label=(alph*)., series=alphenum]
    item First item
    item Second item
  end{enumerate}
  And then you want to continue the first?
  begin{enumerate}[resume*=denum]
    item Third item
    item Fourth item
  end{enumerate}
  Perhaps you even want to continue the second:
  begin{enumerate}[resume*=alphenum]
    item Third item
    item Fourth item
  end{enumerate}
  Too much work?
  newlist{blist}{enumerate}{1}
  setlist[blist]{leftmargin=0.85cm, label=Barabic*.}
  begin{blist}
    item First item
    item Second item
  end{blist}
  And then you can have something entirely different:
  begin{enumerate}[leftmargin=.3textwidth, label=Roman*)]
    item First Roman
    item Second Roman
  end{enumerate}
  Before continuing:
  begin{blist}[resume]
    item Third item
    item Fourth item
  end{blist}
