li:nth-child(4n) should be corrected to li:nth-child(3n+4)?

I think this correction should be made in the teacher's notes since li:nth-child(4n) is targeting the wrong elements to clear (4th, 8th, 12th, etc.). The list elements that should be cleared are the 4th, 7th, 10th, 13th, etc. In other words, every third list item starting from the 4th element. li: nth-child(3n+4) would be the correct pseudo-class to use in this case.

A more robust solution is to use the selector :nth-child(3n + 1)

Bachtiar Firmansyah , why do you say more robust? I understand in this case it doesn't hurt anything to clear the first li but why is 3n+1 better than 3n+4? Just curious. Thanks for your input.
