Question

The sequence an = one half(2)n − 1 is graphed below:

Answer 1

Find the average rate of change between n = 2 and n = 4.

Answer 2

For this one you will just need to find the slope between the points given by n=2 and n=4. These are (2,1) and (4,4). So just find the slope between these two points and that will give you the average rate of change.

Answer 3

Are you comfortable with finding the slope?

Answer 4

Yes let me do it right now.

Answer 5

I got 3/2.

Answer 6

That is right! Good work!
