    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

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

    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
