WebFormulas are just different ways to describe sequences. Each description emphasizes a different aspect of the sequence, which may or may not be useful in different contexts. For example, we may be comparing two arithmetic sequences to see which one grows faster, not really caring about the actual terms of the sequences. WebFeb 13, 2024 · This a sum of the terms of a geometric sequence where the first term is \(P\) and the common ratio is \(1+r\). We substitute these values into the sum formula. Be careful, we have two different uses of \(r\). The \(r\) in the sum formula is the common ratio of the sequence. In this case, that is \(1+r\) where \(r\) is the interest rate.
