Increasing question

I’m having brain flatus here…

Pattern states:

Inc one st at each end of next and every following 4th row until there are X stitches…

assuming I’m starting with row 1 and using garter stitch for easy example, is that:

1: inc 1, k to end, inc 1.
2-3: K
4: inc 1, k to end, inc 1
5-6: k
7: inc 1, k to end, inc 1

or is it 4th plus the 1st row, like

1: inc 1, k to end, inc 1
2-4 k
5: inc 1, k to end, inc 1
6-8: k
9: inc 1, k to end, inc 1

Thanks so much!

Your second idea is right.

You work 3 rows in between the inc rows.
