(d)
The series
(d)
Answer to Problem 2RE
The series converges conditionally at x = -7.
Explanation of Solution
Given information:
The given series is,
Formula used:
Ratio test is used.
Calculation:
From equation (2), the series converges conditionally at x = -7. Since, the rearrangement of the terms affects the convergence of the series x = -7.
Conclusion:
The series converges conditionally at x = -7.
