title: Creating a sequence in a list
body: <p>I am very new to Erlang and I have a question about this function that returns a list counting down in ones. e.g. [3,2,1]</p>
  
  <p>Why doesn't it work if you change the N-1 to N-2?</p>
  
  <p>I'm looking to get the output to show [7,5,3,1]</p>
  
  <pre><code>-module(create_list).
  -export([create_list/1]).
  
  create_list(0) -&gt;
         [];
  
  create_list(N) -&gt;
      [ N | create_list(N - 1) ].
  </code></pre>
