Please help

Hi I’m new to knitting and this forum. My pattern read as follow.
Cast off 2sts at beg of next 4 rows = 94sts (I’ve done it no problem)
Dec 1st at each end of next 2alt rows = 90sts
Does it mean the next row I go through without decreasing and the next I decrease? And won’t I be left with 92sts?

Welcome to the forum and to knitting!
Yes, you want to work one row without decreasing and then decrease on the next row. Since the pattern says the next 2 alternate rows, work one more row plain (no decs) and then work a decrease row. That’ll bring you to 90sts.
Stitch counts at the end of the row are such a big help.

Thank you😊
