|---|---|---|---|---|---|
| annuity | An annuity is an investment that is a sequence of equal periodic deposits. | ||||
| arithmetic sequence | An arithmetic sequence is a sequence where the difference between consecutive terms is constant. | ||||
| common difference | The difference between consecutive terms in an arithmetic sequence, \(a_n−a_{n−1}\), is \(d\), the common difference, for \(n\) greater than or equal to two. | ||||
| common ratio | The ratio between consecutive terms in a geometric sequence, \(\frac{a_n}{a_{n−1}}\), is \(r\), the common ratio, where \(n\) is greater than or equal to two. | ||||
| finite sequence | A sequence with a domain that is limited to a finite number of counting numbers. | ||||
| general term of a sequence | The general term of the sequence is the formula for writing the \(n\)th term of the sequence. The \(n\)th term of the sequence, \(a_n\), is the term in the \(n\)th position where \(n\) is a value in the domain. | ||||
| geometric sequence | A geometric sequence is a sequence where the ratio between consecutive terms is always the same | ||||
| infinite geometric series | An infinite geometric series is an infinite sum infinite geometric sequence. | ||||
| infinite sequence | A sequence whose domain is all counting numbers and there is an infinite number of counting numbers. | ||||
| partial sum | When we add a finite number of terms of a sequence, we call the sum a partial sum. | ||||
| sequence | A sequence is a function whose domain is the counting numbers. |
