This makes no sense, "the first term the sequence must be in descending order". For descending order you have to look at the first tem, second term, and so on.foo9008 said:
The Alt Test, also known as the Alternating Series Test, is a mathematical test used to determine whether an infinite series converges or diverges.
The Alt Test states that if the terms in an infinite series alternate in sign and decrease in absolute value, then the series will converge. This means that if the terms are getting smaller and smaller, the series will eventually reach a finite sum.
The Alt Test is important because it provides a simple and efficient way to determine whether an infinite series converges or diverges. This is useful in many areas of mathematics, such as calculus and differential equations.
A convergent series is one that has a finite sum, meaning that it approaches a specific value as you add more and more terms. On the other hand, a divergent series is one that does not have a finite sum, meaning that it either approaches infinity or oscillates between different values as you add more terms.
The Alt Test can be used in real-world applications to determine the behavior of certain systems, such as electrical circuits or population growth models. It can also be used to analyze the accuracy and convergence of numerical methods in solving mathematical problems.
