Trouble reading a pattern - Sleeves

[sugcu]

Hi all,

I have finished back and front of pullover. But I stuck on sleeves pattern

Pattern says:
Sleeves
.........

Work in st st, inc 1 st at beg and end of every 4th row 8 (7, 8, 7) times, them every 6th row 7 (8, 8, 9) times — 57 (57, 63, 63) sts. Continue without shaping until piece measures 20" (21", 22", 22") from beg. BO.
My question is; Is there missing any word on the bold sentence ?
It says: "them every 6 th row", them what? Is it inc, decrease,knit, purl?
Thanks in advance

So, I will inc 1 st at beg and end of every 4 th row 8 times also I will inc 1 st at beg and end of every 6 th row 7 times

Am I right?

Thanks

Do the increases every 4th row for 8 times then switch over to doing the increases every 6th row. Don't try to mix them up doing incs every 4th row and every 6th row. You'll be increasing more often at first, then not so much as you go up the sleeve. Look at your arm and see how it's shaped....

Yes, it makes sense.
I made a excell chart in order not to mix.

Thanks again
