Answer:

see explanation

Step-by-step explanation:

To calculate the first 3 terms substitute n = 1, 2, 3 into the n th term formula

(a)

8 - 1 = 7

8 - 2 = 6

8 - 3 = 5

The first 3 terms are 7, 6, 5

(b)

8 - 9 = - 1 ← first negative term

1hr 10mins for Katrina. so that's only a gap of 20minutes not half an hour.

So if the destination was 120miles away it would take Mia 2 hours and Katrina 1hour 30mins that is a gap of 30mins.
