title: Regex to match a number sequence like 1 2 3
body: <p>I want to capture number sequences like <strong>1 2 3</strong> or <strong>45 78 63</strong>. I have been trying to create a regex that matches the sequence for a while.</p>
  
  <p>I managed to write a regular expression pattern <code>(\b\d+\b\s){3,}</code>.</p>
  
  <p>But the above pattern matches <code>1 2 3</code> and not <code>45 78 63</code>. Another problem with my pattern is that the captured group includes a trailing whitespace character.</p>
