Answer:
3 and 4
Step-by-step explanation:
Answer:
= 3n - 1
Step-by-step explanation:
Note there is a common difference d between consecutive terms in the sequence, that is
5 - 2 = 8 - 5 = 11 - 8 = 14 - 11 = 3
This indicates the sequence is arithmetic with n th term
= a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 2 and d = 3, thus
= 2 + 3(n - 1) = 2 + 3n - 3 = 3n - 1
The formula d = rt describes distance traveled in time and rate of speed. However, we only have the distance and time to place in. This means d = rt would become d / t = r. Once filled in, the problem is now 76 / 1.5 which equals 50.6 (repeating bar over the 6). However, this is the AVERAGE speed of the truck (meaning we are rounding. 50.6 rounded to the nearest speed would be 51 miles per hour.
