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.

Oct 6, 2021 · The sum of the terms of an arithmetic sequence is called an arithmetic series. We can write the sum of the first \(n\) terms of an arithmetic series as: \[S_n=a_1+(a_1+d)+(a_1+2d)+...+(a_n–d)+a_n. \nonumber \] We can also reverse the order of the terms and write the sum as \[S_n=a_n+(a_n–d)+(a_n–2d)+...+(a_1+d)+a_1. \nonumber\]

A sequence in which every term is created by adding or subtracting a definite number to the preceding number is an arithmetic sequence.
A sequence in which every term is obtained by multiplying or dividing a definite number with the preceding number is known as a geometric sequence.
A series of numbers is said to be in harmonic sequence if the reciprocals of all the elements of the sequence form an arithmetic sequence.
Fibonacci numbers form an interesting sequence of numbers in which each element is obtained by adding two preceding elements and the sequence starts with 0 and 1. Sequence is defined as, F0 = 0 and F1 = 1 and Fn = Fn-1 + Fn-2 Also, see:
Sep 6, 2024 · If the sequence is a 1, a 2, a 3, … , a n the expression a 1 + a 2 + a 3 + … + a n is called the series associated with it. A series is represented by ‘S’ or the Greek symbol [Tex]\displaystyle\sum_{n=1}^{n}a_n[/Tex]. The series can be finite or infinite. Examples: 5 + 2 + (-1) + (-4) is a finite series obtained by subtracting 3 from ...
Sequences can be described in different ways, such as an explicit formula, a recurrence relation, or a table of values. An explicit formula gives a direct way to compute each term in the sequence. A recurrence relation expresses each term in terms of one or more preceding terms.
