What is the fifth term of the geometric sequence 5, 15, 45

Solution:

Given geometric sequence is 5,15,45

The first term is 5 and the common difference is 15/5 = 45/15 = 3

The second term is 15, we can write it as 5(3)

The third term is 45, we can write it as 15(3)

It is the product of the previous term and 3

Hence, the next term would be the product of 45 and 3

It is 135

The fifth term would be the product of 135 and 3

Therefore, it is 405

What is the fifth term of the geometric sequence 5, 15, 45

Summary:

The fifth term of the geometric sequence 5, 15, 45 is 405.
