"Continue diividing for raglan & DIVIDE FOR NECK as foloows: k2tog,patt 20[23,27.31]"
this means that you should knit 2 stitches together, then continue in the established pattern for the given number of stitches.
(The pattern was established earlier: K one row, K1 *P1 K1bw repeat from * til last two stitches then P1 K1)
Hope that helps!
PS -- you might want to remove the copy of the pattern you uploaded to your post -- it violates the copyright that's printed on the bottom of the patttern. (and you never want to upset all those pattern people )
