Series is the sum of a sequence which one gets when he adds up. Though the words series and sequence are common words of english language they find interesting application in mathematics where we encounter series and sequences. They are very similar to sets but the primary difference is that in a sequence, individual terms can occur repeatedly in various positions. The terms series and sequence are used interchangeably in common and informal practice. Sequence first of all, when talking about a sequence, it.

Foremost, when one talks about a sequence, it simply means a list or file of numbers or terms. An arithmetic sequence is a sequence of numbers such that the difference of any two successive members of the sequence is. The sequence is defined as the collection of numbers or objects that follow a definite pattern. How to tell the difference between a sequence and a series. Difference between series and sequence sequence and series are encountered in mathematics.
Arithmetic sequences and series algebra 2, sequences and series. The terms series and sequence are often used interchangeably in common and nonformal practice. A sequence is a list of numbers or terms, while a series is a sum of numbers. However, they are very different concepts from each other. What are the differences between a series and a sequence. In the sequence it is important that there is always an order or pattern, but in the series this is not absolutely necessary. In the sequence the sum is not important, as opposed to the series. Sequence and series are one of the basic topics in arithmetic.

A sequence is a list of values considered as individual terms. Menu algebra 2 sequences and series arithmetic sequences and series an arithmetic sequence is a sequence of numbers such that the difference of any two successive members of the sequence is a constant.
A sequence in mathematics is what is usually called a series in ordinary speech. Difference between sequence and series with comparison chart. What is the difference between a sequence and a series. The most important difference between sequence and series is that sequence refers to an arrangement in particular order in which related. The sum of terms of an infinite sequence is called an infinite series. The elements can be anything and do not need to be numbers. A sequence can be defined as a function whose domain is the set of natural numbers. Students do not understand the difference between series and sequence and sometimes pay dearly with their marks being deducted when they use these terms. Sequences and the corresponding series can be based on a fixed number of terms or an infinite number. In a series, when mathematicians talk of convergence they mean that the infinite sequence sums to a finite number. Series can be arithmetic, meaning there is a fixed difference between the numbers of the series, or geometric, meaning there is a fixed factor. A sequence may be named or referred to by an uppercase letter such as a or s.
Sequences are of many types and most popular are arithmetic and geometric. There are many interesting properties of sequences and series, some of which i have introduced here, but the basic difference between the two is that a sequence is simply a list of numbers, whereas a series is a sum of numbers. Arithmetic sequences and series algebra 2, sequences and. For example the english alphabet is an extremely well known sequence. A finite sequence has a starting number, a difference or.
