Answer:
6, 8, 11, 1, 7, 14, 10, and 10, 6, 9, 14, 1, 6, 12, 7
Step-by-step explanation:
The second and third
1, 3, 7, 21!
Let the first term be a(0). Then the formula for a(n) is a(0)-18(n-1).
Check: What's the first term? Let n = 1: a(1) = a(0)-18(1-1) = a(0) (correct)
What's the second term? Let -n =2: a(2) = a(0)-18(2-1) = a(0) - 18
and so on.

133 1/3 km/hour
Average speed is computed as ...
average speed = (total distance)/(total time)
= (80 km +120 km +200 km)/(2/3 + 1 + 1 1/3 hour) = 400 km/(3 hour)
= 133 1/3 km/hour
