How to put a line number every line of algorithmic

Question

I am looking for a way to have a number for every line in algorithmic:

\documentclass{article}
\usepackage{algorithm} 
\usepackage{algorithmic}
\begin{document}
    \begin{algorithm}
        \caption{Some alg}
        \begin{algorithmic}
            \REQUIRE a,b, c
            \STATE d = a + b + c
            \STATE d = d/2
            \STATE d = d/3
            \RETURN d
        \end{algorithmic}
    \end{algorithm}
\end{document}

I would like to have:

 Require: a,b,c
1 d = a + b + c
2 d = a + b + c
3 d = d/2
4 d = d/3
  return d

Answer 1

According to the manual you can do this the following way:

An optional argument to the \begin{algorithmic} statement can be used to turn on line numbering by giving a positive integer indicating the required frequency of line numbering. For example, \begin{algorithmic}[5] would cause every fifth line to be numbered.

Obviously, \begin{algorithmic}[1] causes a number for every line.
