Just plug in 3 for n and then 5 for n to see if an turns out to be 10 and 26.
n=3:
A) an = 8*3+10 = 34
B) an = 8*3 - 14 = 10 OK
C) an = 16*3+10 = 58
D) an = 16*3 - 38 = 10 OK
n=5:
B) an = 8*5-14 = 26 OK
D) an = 16*5 - 38 = 42
So the answer is B

Answer:
(6,-34)
Step-by-step explanation:
You can use the vertex formula to find the x of the vertex and then plugin the x value into the formula to find the y value.




Now plugin 6 into y=x²-12x+2
y=x²-12x+2
y=6²-12(6)+2
y=36-72+2
y=36-72+2
y = -34
Vertex = (6,-34)
