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. WebPlug the values into the alternative arithmetic series formula. This is the system of equations that we are going to solve by the Elimination Method. Multiply equation #1 by -12 −12. Then add it to equation #2. We get …

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. bus weston super mare to minehead
