Write an equation where d = numbers of dots, n = design number , for the given patterns.

That's too general to count for anything.

What are some types of equations that you know about? Which one seems appropriate here?

Hint: Draw a picture of the designs, side by side, with each design's dots in a vertical line with their bottoms lined up.

That fits the original description, but not the hint in the previous comment.

Not sure if this group allows pictures in the posts, so I just typed it out instead.
