Let's see if we can't be logical here......Pick a formula and see what it yields. For example, choose D.
For n = 1 ---> -1 x 4^1 ----> -1 x 4 = -4, when the correct value is 1. Therefore D is out.
Try C. For n = 1 ---> 1 x 4^(1-1) ---> 1 x 4^0 ----> 1 x1 ---> 1, So it is correct for n =1. How about
n=2? 1 x 4^(2-1) = 1 x 4^1 = 1 x 4 = 4, when the correct answer is -4. Therefore C is out
I'm sure you can do the remaining two choices....

Answer:
-2 and 12
Step-by-step explanation:
It can't be 6 and -4 because 6-4=2
It can't also be -3 and 8 because -3+8=5
It can't be 1 and -24 because 1-24=-23
It can't be 2 and -12 because 2-12=-10
It can't also be -1 and 24 because -1+24=23
It can only be -2 and 12 because -2 + 12= 10
