Answer: 270.9 miles.
Step-by-step explanation:
The formula we use here is :

Given : Ashton used 12.6 gallons of gasoline to drive his car on a weekend trip. he averaged 21.5 miles per gallon.
Then 
Hence, he traveled 270.9 miles.
Each increases by a certain amount called the common difference
4.4-2.8=1.6
6-4.4=1.6
7.7-6=1.7
hmm, some error
maybe you meant 7.6
common difference is 1.6
answer is C
3,000,000+28,000+2=3,028,002
Thye have to have like denominators.
So it becomes, 6/15+5/15 which is equal to 11/15
