Question

The first five terms of a sequence are given.6,2,2/3,2/9,2/27. What equation describes the nth term of the sequence?

Answer 1

what is the sequence ??

Answer 2

6, 2, 2/3, 2/9, and 2/27

Answer 3

do you have choices

Answer 4

yeah, t(n)=6n
t(n)=2*(3)^n
t(n)=18(1/3)^n
t(n)=16(1/3)n

Answer 5

ok the one that makes sense is the 3rd choice 18(1/3)^n

Answer 6

if you look at the numbers the sequence goes by multiplying by 1/3

6 x 1/3 = 2
2 x 1/3 = 2/3
2/3 x 1/3 = 2/9
2/9 x 1/3 = 2/27 and so on

Answer 7

thanks!
