It is not D, because the difference between 2 and -2 is -4, and the difference between -2 and 2 is positive 4.

And it is B because the numbers maintain a constant difference between each other, which is -3.

If f(x)=5x+1 and g(x)=2f(x)+5 then g(-1)=
ollegr [7]
We know f(x)=5x+1. Plug in f(x) in the g(x) function.
We get g(x)=2(5x+1)+5 Distribute the 2 to 5x and 1.
g(x)=10x+2+5
Simplify to get g(x)=10x+7
Now, we plug in -1 for x.
g(-1)=10(-1)+7
g(-1)=-10+7
g(-1)=-3
