Reading Pattern

Hi I’m new to knitting and I have this pattern that I can’t understand. Could someone please explain it to me easier please.

CREATE
SHRUG
Using 6.50mm (US 101/2) (UK 3)
Needles , cast on 99 (107) sts
BEG PATT - 1st row (RS) - *K2, P2, Rep
from *to last 3 sts, K2, P1
Last row forms patt throughout
Cont in patt until work measures 85 (90) cms/33 (35) ins from beg, working last rows on WS.
Cast off loosely in patt

Welcome to KH!
After the cast on, repeat the sequence, Knit 2, Purl 2 up to the last 3stitches, then K2, P1. Turn at the end of the row and repeat the same row for every row until you have the desired length.
