Answer:
2.5+7.5+-10n+-20
Step-by-step explanation:
Multiply everything on the inside by the number on the outside and put it together with addition signs.
-2.5(-3+4n+8)
-2.5*-3=7.5
-2.5(7.5+4n+8)
-2.5*4= -10
-2.5(7.5+-10n+8)
-2.5*8=-20
-2.5+7.5+-10n+-20

I think that is the answer because it says 2/5 where two rows are shaded and three more rows remain unshaded so, when you add that three and two it's altogether 5, so I think that is the answer, please check out the document I have uploaded.
If you divide the distance by the gas used you are able to derive a common ratio, which will give you the constant.
24/1.5 = 16
40/2.5 = 16
96/0.6 = 16
The constant is 16
You subtract 1/6 to get 6.
37/6 = 6 1/6.
If you remove 1/6, you get 6.
