Question

MEDAL/FAN PLEASE HELP!
Which sequence is modeled by the graph below?

Answer 1

Calculate n=1 and n=2 for An first

Answer 2

How do you do that?

Answer 3

The correct answer will give you the correct corresponding values from the graph

Answer 4

For example the first choice...
First Point to the left... n=1, An=4

\[An=(-4)*(-5)^{1-1} = (-4)*(1) = -4\]

Not the right equation... try the next one

Answer 5

Is it the second one?
An=(−4)∗(1/5)2−1=0.8^1=0.8

Answer 6

yes that is the right calculation for n=2, and it matches the graph point (n,An)

Try the other 2 points and double check... for n=1 and n=3
