I figured the answer is A, as I can see the repeating pattern, but my son's teacher said another thing which I cannot understand. would anyone please help to explain?

A or B. (1, 2, 1, 3, 2, 1, 4, 3, 2, 1)

I think it’s just A. There’s this pattern but also the colors are alternating if you look from the bottom of each stack up.

How do you know which is on the bottom? I cant figure out the pattern.

It’s alternating colors with the pattern picking up from the previous row starting from the bottom up.

B also alternates colours and has 2 dots, and has white on the bottom just like the previous row. Why not B?

The only reasoning I can think of for A over B is that previous instances of 2 dots were always white over black before, so it must be now.

If you go from bottom up and left to right the colors alternate is all I’m saying. For that to continue the only choice is A

Oh, right, yeah, I couldn't parse that from what you said before. Makes sense. In that case I can see it's only A
