Answer:
she goes 60mi for every hour for 2 hrs.
then she stops for 30 min which means the line = flat.
After that she drives at 30mi for every hour, but because she drives for 1 hour only, that’s 30 mi, so the line stops in the middle of the square (aka 30 mi after the stop time she took for her flat tire).
An = -4 + (n - 1)(7)
This being in the form of the explicit rule for an arithmetic sequence you can pick out the d and a1.
an = a1 + (n - 1)(d)
d = 7
a1 = -4
