Solutions

Expert Solution

Consider the following infinite series:

Σm=14m-1

 

Check whether the above series is geometric or not.

 

The given series is an exponential function with a base of 4. So, the given series will be a geometric series with common ratio of 4.

Common ratio of the series will be r = 4.

 

The common ratio of given geometric sequence is greater than 1. That is, the common ratio does not lie between -1 and 1.

 

As the common ratio of above geometric series is greater than 1, the sum of above infinite series is “Not Defined.”


As the common ratio of above geometric series is greater than 1, the sum of above infinite series is “Not Defined.”
