WHY IS THE ANSWER A ? ? PLEASE NEED HELP

[Keo]

Flip the graph around its an increasing trend, this also shows that r > 1, it can't be c because it curves again. It increases negatively instead of positively. Good luck tomorrow!

[DannyN]

remember the question doesnt state whether your initial value is postive or negatiuve, hopefully im explaining the right question doing this from memory, i remember every question in 08 onwards >.>

r>1 however "a" may be negative

Let's suppose a = -2 and r =2

t1 = ar^(n-1)
t1 = -2
t2 = -4
t3 = -8

Hope this helps
