Sigma Notation, also known as summation notation, is a mathematical representation of a series of numbers. It is denoted by the Greek letter sigma (Σ) and allows for the compact expression of a sum of terms.
The Sigma Notation is read as "the sum of". For example, Σx2 is read as "the sum of x squared".
The purpose of Sigma Notation is to simplify the representation of a series of numbers, especially when the number of terms is large. It also allows for easier computation of sums and easier identification of patterns in a series.
A string of numbers is a sequence of numbers in a specific order. It can be finite or infinite and can include positive, negative, and decimal numbers. An example of a string of numbers is 1, 3, 5, 7, 9, 11...
Sigma Notation is a way to represent a string of numbers in a concise and organized manner. The series of numbers can be written in Sigma Notation by defining the starting and ending terms of the series and the pattern or rule for generating the terms.
