K2, P2tog,YO - K2, P2tog,YO - K2, P2tog,YO - K2 P2tog,YO - K2, P2tog,YO - K2, P2tog,YO -
K2, P2tog,YO - K2, P2tog,YO - K2, P2tog,YO - K2, P2tog,YO - K2, P2tog,YO - K2, P2tog, YO = 48
As the next row would be row 1 again
1st row - K2 p2 ~~~ turn the work, bring the working yarn toward the front so it will make the YO as you do the first K2.
This is the way I would do it.
Hope it works out for you.
