Increase question

#1

I’ve started an afghan and can’t figure out this row:

K2, k2tog, k2, inc 1 in next 2 sts, k3, k2tog; rept from to last 2 sts, k2

I understand everything but “inc 1 in next 2 sts” - from * to * should end up 11 stitches. I can’t figure it out

You increase 1 stitch in each of the next 2 stitches. You can increase several different ways. Does the pattern tell you what type of increase to use?

#3

When a pattern says to inc [I]in[/I] a stitch you would use a kfb. So you do the row like this -
K2, k2tog, k2, kfb, kfb, k3, k2tog; rept from to last 2 sts, k2
