WebOct 6, 2024 · Two common types of mathematical sequences are arithmetic sequences and geometric sequences. An arithmetic sequence has a constant difference between each consecutive pair of terms. This is similar to the linear functions that have the form y = m x + b. A geometric sequence has a constant ratio between each pair of consecutive …
WebOct 6, 2024 · A geometric series is the sum of the terms of a geometric sequence. The \(n\)th partial sum of a geometric sequence can be calculated using the first term \(a_{1}\) and common ratio \(r\) as follows: \(S_{n}=\frac{a_{1}\left(1-r^{n}\right)}{1-r}\). WebThe standard formula of the geometric sequence is This is an easy problem because the values of the first term and the common ratio are given to us.
