Bernat knit baby jacket set

Hi I’m making a baby cardigan but a little confused the pattern reads rep 2nd and 3rd rows 10 times more 148 St’s does this mean work 20 rows in total or 10 rows ?

I’d take the easy way and work the increase rows until I had the right stitch count. Someone will undoubtedly be able to actually answer your question.

It’ll take 20 more rows but I agree with GG. Easiest way is to count the total sts till you get to 148sts.
