Answer:
![\large\boxed{a_n=3n-10}](https://tex.z-dn.net/?f=%5Clarge%5Cboxed%7Ba_n%3D3n-10%7D)
Step-by-step explanation:
It's an arithmetic sequence.
![-4-(-7)=-4+7=3\\-1-(-4)=-1+4=3\\2-(-1)=2+1=3\\5-2=3](https://tex.z-dn.net/?f=-4-%28-7%29%3D-4%2B7%3D3%5C%5C-1-%28-4%29%3D-1%2B4%3D3%5C%5C2-%28-1%29%3D2%2B1%3D3%5C%5C5-2%3D3)
The difference is constant.
The explicit formula of an arithmetic sequence:
![a_n=a_1+(n-1)d](https://tex.z-dn.net/?f=a_n%3Da_1%2B%28n-1%29d)
Substitute:
![a_1=-7,\ d=3](https://tex.z-dn.net/?f=a_1%3D-7%2C%5C%20d%3D3)
<em>use distributive property</em>
![a_n=-7+3n-3\\\\a_n=3n+(-7-3)\\\\a_n=3n-10](https://tex.z-dn.net/?f=a_n%3D-7%2B3n-3%5C%5C%5C%5Ca_n%3D3n%2B%28-7-3%29%5C%5C%5C%5Ca_n%3D3n-10)
Answer:
x = -19
Step-by-step explanation:
-3= 12x-5(2x-7)
Distribute
-3= 12x-10x+35
Combine like terms
-3 = 2x +35
Subtract 35 from each side
-3-35 = 2x+35-35
-38 = 2x
Divide each side by 2
-38/2 = 2x/2
-19 =x
Angle 3 is equal to angle 5 because of vertical angles.
