Using the graph below, what is the common ratio of the geometric sequence?
a. r = 8
b. r = 4
c. r = 1/4
d. r = −24

As your n value increases, your t_n value is divided repeatedly by 4. You can find the common ratio here by divided one term in the sequence by the one before it; 8/32 and 2/8 both produce the same ratio - 1/4 - so it’s safe to assume that 1/4 is your common ratio.

It's like discovering the answer to a puzzle. the purpose in solving an equation is to find the value or values of the variable that makes it a true statement. any value of the variable that makes the equation true is called a solution to the equation.
