rib 6 would meen to rib over 6 stitches (p2, k2, p2)
you then do a decrease which is the k2tog (knitting two stitches together as one).
Repeat these steps until the end of the row.
on the following row there are no decreases, just continue in the ribbing you have established by knitting the knits (the 'v' ) and purling the purls (the '-' bumps)
