Need help with Sock pattern

[Maria]

I am making the Bernat Sox in the Finished Foot Length of 9 inches. I am having a problem with this pattern. I have made my heel and am now trying to shape it. The pattern says to:
Row 1 Purl 16, P2tg, P1, turn
Row 2 K3, S1, K1, psso, K1, turn
Row 3 P4, P2tg, P1, turn
Row 4 K5, S1, K1, psso, K1, turn
Cont in same manner to 17 sts.

I have done these 4 rows. I do not have enough stitches to repeat from Row 1. Also, by decreasing 4 stitches each time through, you cannot get from 31 to 17 stitches. Please help, I'm confused.

You are not actually repeating from row one. You are to continue therefore Row 5 is P6, P 2 tog., P1 turn
Row 6 would be K7,S1, K1, psso.,K1, turn. On each row you are either Purling or Knitting 1 extra st before you do the decrease. Hope you can undertand what I mean.

Thank you so much - I think I get it now. I keep going P6, K7, P8 etc. I'm excited to go and try it. Thanks again.
