Understanding the Infinite Geometric Series Calculator
An infinite geometric series calculator is an online tool that simplifies the calculation of the sum of an infinite geometric sequence. A geometric sequence is a sequence of numbers where each subsequent term is obtained by multiplying the previous term by a constant known as the common ratio. The infinite geometric series calculator performs this calculation by applying the formula:
Sum = a / (1 - r)
where:
- a is the first term of the series
- r is the common ratio
