Final answer:
In mathematics, the series written in sigma notation is a way to represent the sum of a sequence of numbers using the sigma symbol, Σ.
Step-by-step explanation:
In mathematics, the series written in sigma notation is a way to represent the sum of a sequence of numbers. The sigma symbol, Σ, is used to indicate that we are summing up the terms of a sequence. Here is an example:
Σn14 n = 1 + 2 + 3 + 4 = 10
In this example, Σn14 n represents the sum of the numbers 1, 2, 3, and 4. The lower limit of the summation is 1, and the upper limit is 4. The variable n takes on the values from 1 to 4, and we sum up these values to get 10.
