A finite sequence is a sequence whose domain consists of only the first \(n\) positive integers. The numbers in a sequence are called terms. The variable \(a\) with a number subscript is used to represent the terms in a sequence and to indicate the position of the term in the sequence. \[a_1,a_2,a_3,…,a_n,…\]
A "series" is what you get when you add up all the terms of a sequence; the addition, and also the resulting value, are called the "sum" or the "summation". For instance, "1, 2, 3, 4" is a sequence, with terms "1", "2", "3", and "4"; the corresponding series is the sum "1 + 2 + 3 + 4", and the value of the series is 10.
Sequences. Number sequences are sets of numbers that follow a pattern or a rule. If the rule is to add or subtract a number each time, it is called an arithmetic sequence. If the rule is to ...
Each number in the sequence is called a term. The first five terms of this sequence are 2, 4, 8, 16, and 32. Listing all of the terms for a sequence can be cumbersome. For example, finding the number of hits on the website at the end of the month would require listing out as many as 31 terms.
Oct 6, 2021 · Formulas are often used to describe the \(n\)th term, or general term, of a sequence using the subscripted notation \(a_{n}\). A series is the sum of the terms in a sequence. The sum of the first \(n\) terms is called the \(n\)th partial sum and is denoted \(S_{n}\).
