Consider the power series \[ \sum_{n=1}^{\infty} \frac{(3 x-1)^{n}}{n^{2}} \] Find the radius of convergence \( R \). If it is infinite, type "infinity" or "inf". Answer: \( R= \) What is the interval of convergence? Answer (in interval notation):

          Consider the power series
\[
\sum_{n=1}^{\infty} \frac{(3 x-1)^{n}}{n^{2}}
\]

Find the radius of convergence \( R \). If it is infinite, type "infinity" or "inf".
Answer: \( R= \)

What is the interval of convergence?
Answer (in interval notation):

Consider the power series

∑n=1^∞((3 x-1)^n)/(n^2)

Step 1

The Ratio Test states that for a series \(\sum a_n\), if \(\lim_{n \to \infty} \left| \frac{a_{n+1}}{a_n} \right| = L\), then the series converges if \(L < 1\), diverges if \(L > 1\), and is inconclusive if \(L = 1\). Show more…
