C - (x-3)^2=36
If we expand (x-3)^2=36:
(x-3)(x-3)=36
x^2-3x-3x+9=36
x^2-6x+9=36
Then subtract 36
x^2-6x-27=0
-1 - (-7) = 6
5 - (-1) = 6
11 - 5 = 6
The common difference is 6.
If you add 6 to a term, you get the next term.

Answer: 3/8
Step-by-step explanation: If you put it into the slope formula, you would get 18 - 9 / 19 - (-5) which simplifies to 9/24 and then to 3/8.
