How do you add the fourth element first then every third after that

Regarding img:nth-child(4n+3)

style.css 
/* Write the CSS in the media query below */

@media (min-width: 607px) {
  img
  {
    float: left;
  }
  img:nth-child(4n+3)
  {
    float: left clear; 
  }
}
index.html 
<!DOCTYPE html>
<html>
<head>
    <title>Selectors</title>
  <meta name="viewport" content="width=device-width, initial-scale=1">
  <link rel="stylesheet" href="page.css">
  <link rel="stylesheet" href="style.css">
</head>
<body>
    <img src="thumb-forest.jpg" alt="">
    <img src="thumb-resort.jpg" alt="">
    <img src="thumb-trees.jpg" alt="">
    <img src="thumb-falls.jpg" alt="">

Looks like you accidentally reversed them! the first '4n' refers to the value to 'skip over', and the '+ number' refers where to start!

what you're looking for is :nth-child(3n + 4)!

Let me leave this awesome resource here for you to play around with! http://nth-test.com/
