Answer:
= 103 - 3n
Step-by-step explanation:
there is a common difference between consecutive terms , that is
97 - 100 = 94 - 97 = 91 - 94 = - 3
This indicates the sequence is arithmetic with explicit equation
= a₁ + (n - 1)d
where a₁ is the first term and d the common difference
here a₁ = 100 and d = - 3 , then
= 100 - 3(n - 1) = 100 - 3n + 3 = 103 - 3n
Answer:
a). Mileage for carA= , and mileage for carB=
b).total mileage for both is similar to average of them=
=
Step-by-step explanation:
It is given that the distance traveled by car
And distance traveled by car
We know the mileage is mile/gallon,
a).So mileage of car
Similarly , the mileage for car
b).total mileage for both is similar to average of them=
Now divide by 2 for total(average) mileage.
.
Thus those are the answers.
