What sequence is modeled by the graph below? coordinate plane showing the points (2,1) (3,2) (4,4) (5,8) a an = 2(2)n − 1 b an = 2( one half )n − 1 c an = 4(−2)n − 1 d an = one half (2)n − 1

ANSWER

EXPLANATION

The corresponding ordered pairs from the graph are:

(2,1) (3,2) (4,4) (5,8)

The y-values are:

1,2,4,8

The first term term is the term before 1,this has to be.

The common ratio is

The nth term is given by

Let's substitute the values to get,

This simplifies to,

the answer is 0.3175 hope that you ^w^

also you might actually want to put this picture up if you want people to solve it luckily i remember this question
