## anonymous one year ago The points shown on the graph represent the numbers in a geometric sequence. What is the initial value of the sequence?

1. anonymous

2. freckles

reading from left to right the initial point is the first point which is?

3. anonymous

1,2 @freckles

4. freckles

yep (1,2) 1 is where the initial value happens 2 is the actually the initial value

the geometric sequence you see there is... 2,4,8 where the common ratio is 2 and the initial value of sequence is 2 where the sequence can be described as : $a_n=2 (2)^{n-1} \\ \text{ and we see } a_1=2(2)^{1-1}=2(2)^{0}=2(1)=2 \\ \text{ the first number in the sequence is 2 given by n=1 }$
