9. What is the explicit formula for the sequence 400, 100, 25, 6.25, ... ? a. 91 = 400 - 4(n-1)
b. 91 = 400 · 1/4(n-1)
C. 9ı = 400 - 4(n-1)
d. 91 = 400 -4(n-1)

B as Blake Griffin

91 = 400 * 1/4(n - 1)

Step-by-step explanation:

For example plug in 2 for the n. That basically means the 2nd term.

400 * 1/4( 2 - 1)

2 - 1 = 1

1/4 * 1 = 1/4

400 * 1/4 = 100

And what does the second term say...

It also says 100 over there as well.

So therefore I am right.

Blake Griffin is so smart!
