Answer to Problem 8CT
The sum of the sequence is
Explanation of Solution
Given information:
The given sequence is
Calculation:
Calculate the difference between the first and the second terms.
Calculate the difference between the second and the third terms.
Since the difference of the successive terms is not constant, we can say that the given sequence with common difference is
The sum
