Question

What is the r value of the following geometric sequence? 4, 7, 12.25, 21.4375.

Answer 1

to find the common ratio (r) divide the second term by the first term
7 / 4 = 1.75 <==

Answer 2

r ( common ratio) = 1.75

Explanation:

Given : geometric sequence 4, 7, 12.25, 21.4375.

To find : What is the r value .

Solution : We have given

Geometric sequence 4, 7, 12.25, 21.4375.

r ( common ratio) =
`(second\ term)/(first\ term)`.

r ( common ratio) =
`(7)/(4)` = 1.75

r ( common ratio) =
`(12.25)/(7)` = 1.75

Therefore, r ( common ratio) = 1.75
