[jQuery] identifying the nth element and manipulating another nth element

[sperks]

I'm wanting to target the nth <li> in a list after clicking the nth
link.

    <ul id="targetedArea">
      <li></li>
      <li></li>
      <li></li>
      <li></li>
    </ul>
    <div id="clickedItems">
      <a></a>
      <a></a>
      <a></a>
      <a></a>
    </div>

I can target them all individually, but I know there must be a faster
way by maybe passing the what <a> element I clicked on.

    $("#clickedItem a:eq(2)").click(function() {
      $("#targetedArea:eq(2)").addClass('active');
      return false;
    });

Cheers,
Steve
