Are the instructions saying anything about the increase? That is the only thing I think is not clear in these instructions. “Inc in next st” sounds like a PFB or KFB increase because the normal M1 is worked between stitches and not “in next st”.
K19, k2tog, K18, k2tog, K18, k2tog, K18, k2tog, K20 (97 sts)
P18, increase in next st, P19, increase in next st, P19, increase in next st, P19, increase in next st, P18 (101 sts)
Is this what you needed? Please let us know if you need something else explained
