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

Verified Answer :

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

Answer:

r ( common ratio) = 1.75

Step-by-step 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) = \(\frac{second\ term}{first\ term}\).

r ( common ratio) = \(\frac{7}{4}\) = 1.75

r ( common ratio) = \(\frac{12.25}{7}\) = 1.75

Therefore, r ( common ratio) = 1.75
