Answer:7n-1
Step-by-step explanation:
Nth term=6+7(n-1)
Nth=6-7+7n
Nth term=-1+7n
Nth term=7n-1
Answer:
It is the first choice.
Step-by-step explanation:
This is a sequence where
the next term is obtained by adding 6.
first term = -9 + 6(0) = -9
second term = -9 + 6(1) = -3
third term = -9 + 6(2) = 3
4th term = -9 + 6(3) = 9
and 81 = -9 + (6*15).
So the answer is Sigma (-9 + 6n) from n= 0 to n = 15.
At the end of the third day, the new reading on the odometer will be 12,578 mi
<h3>
What will the odometer reading at the end of the third day?</h3>
The initial odometer reading is 12,386 miles.
Then, the driver takes drives to and from work, such that each trip is 32 miles. Then each day he drives 2*2mi = 64 miles.
And he does this for 3 days, then the total distance driven is:
3*64mi = 192 miles.
At the end of the third day, the new reading on the odometer will be:
R = 12,386 mi + 192mi = 12,578 mi
