Help with raglan pattern

Hello.

I’m knitting a jumper for my friends baby and I’m stuck on the raglan instructions.

It stayed I cast off 3 st at the beg of next 3 rows?

But then says start with a rs row but if I do 3 rows next would be a ws I’m a little confused

See below:
Shape raglans: Cast off 3 sts beg next 2
rows. 41 (44-47-49) sts.**
Next row: (RS). K1. ssk. Knit to last 3 sts.
K2tog. K1.
Work 3 rows even.
Rep last 4 rows 1 (1-3-5) time(s) more. 37
(40-39-37) sts.

Help

This is the cast off for the underarms. The pattern actually says to bind off 3 sts at the beginning of the next 2 rows. That’s put you back on a RS row for the next direction.

Oh yeah! Duh! Thank you x
