Did you determine whether it's arithmetic or geometric?

anonymous · Answer

im thinking its geometric

the_fizicx99 · Answer

It is, it has a ratio of 1.1 (1.10)

Use the formula for explicit, it'll say you some time.

a_1 = 32,000
r = 1.1

a_13 = 32,000 $\ \sf \times 1.1^{13} \rightarrow 32,000 \times 1.1^{13}$ 

a_13 = 32000 * 3.4522712143931 = 110,472.6788605792

So B

2002 was when it was 0, 2015 is the estimated date.

13 - 0 = 13
