The correct answer is D, 146 inches.
7 x 12 = 84
4 x 12 = 48
84+48+4+10 = 146
Answer:
![\sqrt[8]{197^{7} }](https://tex.z-dn.net/?f=%5Csqrt%5B8%5D%7B197%5E%7B7%7D%20%7D)
Step-by-step explanation:
![\sqrt[8]{197^{7} }](https://tex.z-dn.net/?f=%5Csqrt%5B8%5D%7B197%5E%7B7%7D%20%7D)
We conclude that the sum of the first 8 terms of the arithmetic sequence is 17/5.
<h3>
How to get the sum of the first 8 terms?</h3>
In an arithmetic sequence, the difference between any two consecutive terms is a constant.
Here we know that:

There are 7 times the common difference between these two values, so if d is the common difference:

Then the sum of the first 8 terms is given by:

So we conclude that the sum of the first 8 terms of the arithmetic sequence is 17/5.
