Write down any two sequential terms of the geometric series, preferably the first two. For example, if your series is 3/2 + -3/4 + 3/8 + -3/16 + .. your can use 3/2 and -3/4. Step 2 Divide the second term by the first term to find the common ratio. To divide fractions,...
‘r’ is the common ratio between each term in the series The sum to infinity of a geometric series To find the sum to infinity of a geometric series: Calculate r by dividing any term by the previous term. Find the first term, a1. Calculate the sum to infinity with S∞ = a1÷ (...
How to find the sum of geometric series Geometric Sequences and Series:A geometric sequence is a list of numbers in which the ratio between each term in the list and the term preceding it is the same. We call this ratio the common ratio of the geometric sequence. When we want to take...
In a geometric sequence, each number in a series of numbers is produced by multiplying the previous value by a fixed factor. If the first number in the series is "a" and the factor is "f," the series would be a, af, af^2, af^3 and so on. The ratio between any two adjacent n...
For example, the root test and ratio test involve taking a limit. While they can tell you something about convergence, they say nothing about the value of the sum [4]. How to Find the Sum of a Series: Example Example question: Estimate the sum of the following series with the 10th ...

The unit step response is a standard tool for experimental identification; its shape is equivalent to a solution of an appropriate governing equation. In this study, we investigate two variants of nonlinear first-order governing equation,y′=k(1−yβ)/β, and mainly its rescaled versiony′=...
