SUMMARY
The series in question is represented by the expression x^n/(2n-1), which has a radius of convergence of 1. The ratio test confirms that the absolute value of x must be less than or equal to 1 for convergence. While both endpoints, -1 and 1, yield convergence when plugged into the original series, the interval of convergence is [-1, 1) due to the divergence of the series at x=1, specifically when evaluated as ##\sum \frac{1}{2n-1}##. This divergence at x=1 necessitates the use of a soft bracket in the interval notation.
