a family has two cars. the first car has a fuel efficiency of 20 miles per gallon of gas and the second has a fuel efficiency of
15 miles per gallon of gas. during one particular week, the two cars went a combined total of 850 miles, for a total gas consumption of 50 gallons. how many gallons were consumed by each of the two cars that week?
Given the pattern: 4,15,7,12,10,9,.. Every other term after the first term is increasing by 3. Thus continuing the pattern we shall have: 4, 15, 7, 12, 10, 9, 13, 11,16 thus the missing numbers will be: 13,11,16
