Answer to Problem 80CR
The common ratio for geometric series
Explanation of Solution
Given:
The sequence is
Calculation:
Divide the second term with the first term of the sequence to obtain the ratio of sequence.
Divide the third term with the second term of the sequence to obtain the ratio of sequence.
Divide the fourth term with the third term of the sequence to obtain the ratio of sequence.
Therefore, the common ratio is
Thus, the common ratio for geometric series
