Select 2nd and 3rd element from each triplet of elements
<p>I have set of 6 elements and I would like to filter by every second and third element so I want to have elements 2, 3, 5 and 6. I've tried <code>.filter(':nth-child(2n+1)'));</code> but obviously that filters the 2, 4, and 6.</p>

<p>The other way I was trying was to remove elements 1 and 4, but I couldn't find a jQuery function that was the opposite of filter that would remove the elements from the set.</p>
