Homework Statement
i need help writing in sigma notaion
the numbers are 5,10,17,26
HallsofIvy said:Okay, the numbers are 5, 10, 17, and 27! What do you want to do with them? Since you mentions "sigma notation" I might guess adding but what exactly is your question?
Sigma notation is a way to represent a series of numbers in a concise and organized manner. It uses the Greek letter sigma (Σ) to indicate a sum, followed by the expression or pattern for the numbers being added.
The expression for this series would be written as Σ(n^2 + 1) where n ranges from 1 to 4. This means that each number in the series is squared and then added to 1.
Sigma notation is used to simplify and condense the representation of a series of numbers. It makes it easier to perform calculations and understand the pattern or formula behind the numbers.
The lower limit of the series is indicated by the number below the sigma symbol and the upper limit is indicated above the sigma symbol. In the example of 5, 10, 17, 26, the lower limit is 1 and the upper limit is 4.
Yes, variables can be used in sigma notation. The expression inside the parentheses can include any mathematical operation or formula using the variable.
