The ratio test is simple, works often, and is used by the calculator on this page so that is what we will learn about here. Our online calculator, build on Wolfram Alpha system is able to test convergence of different series. If the value received is finite number, then the For example, the function $ y = \frac{1}{x} $ converges to zero when x is increased. An arithmetic series is a sequence of numbers in which the difference between any two consecutive terms is always the same, and often written in the form: a, a+d, a+2d, a+3d, , where a is the first term of the series and d is the common difference. Thus, each element in the sequence is half of the previous element. Knowing that: \[ a = \left.
