help please!

hi guys! it’s my first time making a cabled pullover and the pattern is just so confusing.i got the body part done but i’m having a problem understanding about Shaping Raglans.and making sleeves. **SHAPE RAGLANS:keeping cont of pat,cast off 2 sts beg next 2 rows.51 sts. 1ST ROW:K1.SSK.PAT TO LAST 3 STS.K2TOG.K1.
2ND ROW:P1.P2TOG.PAT TO LAST 3 STS.P2TOGBL.P1.repeat 2 rows twice then 1st row once.I should get 37 sts.
NEXT ROW:P2.PAT TO LAST 2 STS.P2.
I just couldn’t understand the PAT TO LAST.
SLEEVES: it has 4 rows to form irish moss st pat,and I did all that.the problem now is this:
WORK 2 ROWS IN PAT.INC 1 ST EACH END OF NEXT AND EVERY FOLLOWING 8TH ROW UNTIL THERE ARE 35 STS,TAKING INC STS INTO IRISH MOSS ST PAT.

CONT EVEN IN PAT UNTIL WORK FORM BEG MEASURES 12 1/2’’,ENDING WITH WS ROW.

THANK YOU IN ADVANCE FOR HELPING!

It’s “pat” that’s got you?

1ST ROW:K1.SSK. Knit in PAT ttern TO LAST 3 STS.K2TOG.K1.

As you increase the sleeves turn the increased stitches into Irish moss as you go.
