Math Problem Statement
Solution
The given problem asks to determine whether the series
converges or diverges.
Solution:
Step 1: Analyze the general term
The general term of the series is:
For large values of , the highest power of in the numerator and denominator dominates. Simplifying the leading terms:
Step 2: Test for divergence
If , the series diverges by the Divergence Test (also called the -th term test for divergence).
Compute the limit:
Divide numerator and denominator by :
As , the terms , , and approach . Thus:
Since , the series diverges.
Conclusion:
The series diverges.
Would you like further explanation or related examples? Here are five follow-up questions to explore:
- What is the Divergence Test, and why is it applicable here?
- How do we determine convergence for series where the Divergence Test is inconclusive?
- Can the Limit Comparison Test be applied to this series for additional verification?
- How does the presence of dominant terms in the numerator and denominator affect convergence?
- What is an example of a series that converges, and how does it differ from this one?
Tip: For rational functions in series, always check the leading terms as to simplify your analysis!
