B as it goes through the correct and average amount of points on the graph, hope this helps
Answer:
1) 2(t+1)(t−7)
2) 7 months
Step-by-step explanation:
The equation of nth term will be written as for n as will be (
- a₁ + d) / d. Then the correct option is D.
The missing options are attached to the picture given below.
<h3>What is a sequence?</h3>
A sequence is a list of elements that have been ordered in a sequential manner, such that members come either before or after.
The formula for the nth term of an arithmetic sequence can be found using the formula given below.
![\rm a_n = a_1 + (n-1)d](https://tex.z-dn.net/?f=%5Crm%20a_n%20%3D%20a_1%20%2B%20%28n-1%29d)
Then arrange the equation for n, we have
![\begin{aligned} \rm a_n - a_1 & \rm = nd - d\\\\\rm a_n - a_1 + d & \rm =nd\\\\\rm n & \rm = \dfrac{a_n - a_1 + d}{d} \end{aligned}](https://tex.z-dn.net/?f=%5Cbegin%7Baligned%7D%20%5Crm%20a_n%20-%20a_1%20%26%20%5Crm%20%3D%20nd%20-%20d%5C%5C%5C%5C%5Crm%20a_n%20-%20a_1%20%2B%20d%20%26%20%5Crm%20%3Dnd%5C%5C%5C%5C%5Crm%20n%20%26%20%5Crm%20%3D%20%5Cdfrac%7Ba_n%20-%20a_1%20%2B%20d%7D%7Bd%7D%20%20%5Cend%7Baligned%7D)
Then the correct option is D.
