Dividing a pattern in half?

I only want this pattern to be half the size but not sure how To divide it and still get the design?? TIA!!

Here is the pattern:

Rows 1-4 knit across

Row 5 (right side) K5, work knit increase, (K2, knit increase) across to last 5 sts, K5. 180 sts.

Row 6: K5 (YO, slip 1, K2, PSSO) across to last 4 sts, K4.

Row 7: K4, purl across to last 4 sts, K4.

Row 8: K4, slip 1, K2, PSSO, (YO, slip 1,K2, PSSO) across to last 5 sts, YO, K5.

Row 9: K4, purl across to last 4 sts, K4

Rpt rows 6-9 for pattern.

Welcome to KnittingHelp!
What is the pattern that you’re making? Can you give us a link or a pattern name?
It looks like a multiple of 3sts + 9, likely a multiple of 3 but it would be good to know the given cast on number to be sure it all works.

Sorry…I thought I put that in there CO 137.

OK, thanks. Yes, the pattern works out if you increase to 90sts in row 5.
How does the pattern define a knit increase?
