The convergence of an infinite series refers to the property that the sum of the terms in the series approaches a finite number as the number of terms increases indefinitely. Conversely, divergence occurs when the sum of the terms becomes infinitely large as the number of terms increases.
To determine the convergence or divergence of an infinite series, you must evaluate the limit of the sequence of partial sums. If this limit exists and is a finite number, then the series is said to converge. If the limit does not exist or is infinite, then the series is said to diverge.
The ratio and root tests are two commonly used tests in determining the convergence or divergence of an infinite series. These tests provide a way to analyze the behavior of the terms in the series and determine if the series converges or diverges based on the values of the terms.
No, an infinite series cannot converge to a negative number. The convergence of a series means that the sum of the terms approaches a finite number, and a negative number is not considered a finite number.
Determining the convergence or divergence of an infinite series is important in various fields of mathematics, such as calculus and differential equations. It allows us to understand the behavior and properties of infinite sums and to make accurate calculations and predictions in real-world applications.
