A sequence is said to be arithmetic if every couple of adjacent elements differ by the same number. If this is the case, that constant number is called the common difference.
This sequence is arithmetic, because the difference between every element and the previous one is
So, the common differnece is 3.4, because every couple of adjacent terms differ by 3.4

![2](https://tex.z-dn.net/?f=2)
Step-by-step explanation:
Given:
![-2(1-4x)=3x+8](https://tex.z-dn.net/?f=-2%281-4x%29%3D3x%2B8)
Let's distribute the parenthesis
![-2+8x=3x+8](https://tex.z-dn.net/?f=-2%2B8x%3D3x%2B8)
Let's subtract
from both sides
![-2+5x=8](https://tex.z-dn.net/?f=-2%2B5x%3D8)
Let's add
to both sides
![5x=10](https://tex.z-dn.net/?f=5x%3D10)
Now, let's divide both sides by
to get
alone
![x=2](https://tex.z-dn.net/?f=x%3D2)
Hope this is helpful
