To see that if the radius are different we really only have the minimum and not more as the ...

We will find the interval of convergence of a power series. Loosely speaking, a power series is a polynomial of infinite degree. For example, ∑n=0∞ xn n + 1 = 1 + x 2 + x2 3 + x3 4 + ⋯. The name power series comes from the fact that we have an infinite series that contains powers of the variable x. In the formal definition of a power ...I was asked to calculate the radius of convergence. We can write the series as: $$\sum {n\over {n+1}}\cdot \left(2+{1\over x}\right)^n$$ Now, we can define $t:={2+{1\over x}}$ and then evaluate the series $\displaystyle\sum {n\over {n+1}}\cdot t^n$. Is there another way I'm expected to think of without using this "trick"?The Radius of Convergence is 1 (from the right side of the inequality). Step 4: Plug your Step 3 answer for R into the interval of convergence formula: (a – R, a + R) = (5 – 1, 5 + 1) = (4, 6). *For a power series, the center is defined in the terms. Look for part of a general term in the series that looks like x – a.The center is “a“. Ratio Test General StepsAssume the power series $$ \sum_{n=0}^∞ x^n $$ at which the center of the series is a = 0, to calculate the radius of convergence, we can use the ratio test. Taking the ratio of successive terms, we get: $$ \lim_{n\to\infty} \left| \frac{x^{n+1}}{x^n} \right|=|x| $$ 2.
