This isn't the sleeve is it, sounds like you're still on the body.
So if it's the 2nd pattern st row (you can be specific and even type out a few of the rows to get help with them). That would be k1 * yo, k2tog * and repeat that until you have 1 st left. Then do it 4 more times, and this is a garter stitch stripe, so you're no longer in stockinette stitch. On the 7th row you do the same k1 * yo, k2tog *4 times total, then knit until there's 9 sts left and yo k2tog until the last stitch, then knit it.
This is an older pattern where you do what's in the **s once, then the repeat is 3 or 4 or whatever more times.
