Help Reading a Pattern

I am knitting a baby beanie on straight needles. There are a few notes in the pattern that I am not sure about. If you could clarify the following directions it would be great!
1.) Purl to end dec 1 sts evenly across row. - where do I decrease 1 stitch?
2.) Next row. *K5, k2tog, rep from * to last st, k1. 37 [43:49:61:67] sts. - are the numbers at the end how many stitches I should have after I complete the row?
3.) Work 3 rows more without shaping. Do I just knit 3 rows?

Thank you so much for your help!

  1. probably about the middle of the row.
  2. yes, that’s the sts left at the end of the row for the different sizes.
  3. Yep. Do another 3 rows in the pattern, no decreases.
