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