As you can tell, they are subtracting 7 cans each row. You could make a table which would be kind of like this with an ordered pair.
1,85
2,78
3,71
and on
Or you can find what 85-29 equals. Once you find 56, you divide it by 7. That gives you 8 but you have to take in consideration that row one has 85 and that is when it started decreasing, so you have to add a 1 to the 8. This allows you to know that it is row 9 that contains 29 cans. You can even finish your table to make sure.
4,64
5,57
6,50
7,43
8,36
9,29
I hope this helps!!
