On the first inc row, work 17 sts in pattern, do the incs then work 40 sts in the pattern. On a RS row, you would probably be ending with k2. Go with the patterning from the previous rows after you do the incs, though it looks like the sts between the markers are a repeat and a half of the pattern, so they're going to do the pattern in a little different spot. You want the pattern to match what's below it. Before the inc, you did a k1, then the new incs and I think after them you would start with k1 also, then yo, p2 tog, k2 and so on. There are no purl sts on row 1 except p2tog.
BTW, could you remove the parts of the pattern that don't pertain to your question? It looks like you posted the entire pattern and that's against copyright law. Just keep the pattern stitches and increase rows in your post. Thanks.
