Sigma Notation (page 1)
Sigma notation is useful because it allows you to write a long series in a compact way. When working with arithmetic
series, you learned that _____ represents the sum of the series. In sigma notation, also called summation notation,
the letter “S” is still used, but it is not the English letter “S”; it is the equivalent Greek letter ____, known as sigma!
Let’s examine the sum of the first six terms of the arithmetic sequence 3, 7, 11 ... (Watch the video)
Fill in the sigma notation below with the lower limit, upper limit, and sequence rule:
Two Ways to Find the Value of the Sum (page 1)
1. The value of this sum is found by either adding the terms of the sequence
2. or by using the arithmetic series formula
