I assume they are looking for an equation?
y = x
where y is the row and x is the number of boxes...

Here's what the hell it means.
Visualize a pyrmaid of boxes, where each row has one less box than the row below it. the top row has 1 box, the next row has 2 boxes, the third row has 3 boxes, etc.
The "rule" you are looking for is, How many boxes will there be in a pyramid with n rows in it?
I don';t have time to explain it. It's n(n+1)/2. Someone else can give you the details.

It probably means you have to right what the pattern is which is adding a box.
