It's 2.7 pounds because I set up a proportion of 150 over 90 = 4.5 over X and multiplied 90 * 4.5 divided by 150
PART A
The geometric sequence is defined by the equation

To find the first three terms, we put n=1,2,3
When n=1,



When n=2,



When n=3



The first three terms are,

PART B
The common ratio can be found using any two consecutive terms.
The common ratio is given by,



PART C
To find

We substitute n=11 into the equation of the geometric sequence.

This implies that,


no. he isn't correct because the scale factor is an improper fraction. 2/5 means you have 2 out of 5, but if you have 8 out of 3, that means you have 2 3s and 2 more leftover. it wouldn't be a reduction, it'd be increasing!
