Please Help with inctructions pk2

I started this project and for one of the rows it states pk2. How do I do that stitch? I cannot find any explanation online. The instructions for the row are k4 k2, pk2 repeat from to last 6 sts, k6.

Sounds like a typo for ‘p2’. Does the picture show what looks like k2 p2 ribbing across the middle of the row?
