The pattern as the instructions have established is the knit panels separated by purl stitches. You wouldn't repeat both of the 2 previous rounds, 1 of them is an increase round and you only do that every 3 inches. So just the previous round. But then after you increase, you'll be doing K16 in every panel instead of K 14. And if you increase again, each panel will be a K 18.
As you work on it, you'll be able to see what it looks like after several inches, and it should be easier to figure out.
