Question

How do you find average rate of change and identify a sequence based on a graph?

Answer 1

HI!
i guess it depends on the graph right?

Answer 2

looks like you are dividing by 2 each time right?

Answer 3

are you trying to find the sequence?

Answer 4

yes, and i have to write the sequence out.

Answer 5

and I have to find the average rate of change from n=0 to n=3

Answer 6

2 gives 10 so 1 gives 20 and 0 gives 40

Answer 7

sequence would be
\[a_n=40\times \left(\frac{1}{2}\right)^n\]if you are starting at \(n=0\)

Answer 8

average rate of change from 0 to 3 would be \(\frac{40-5}{3}\)

Answer 9

great, thank you so much!
