Sum It Up
An arithmetic sequence can be written in sequence notation using the function an = a1 + d(n − 1).
A geometric sequence can be written in sequence notation using the function an = a1 • rn−1.
A geometric series is a sum of a list of numbers with a common ratio. The sum of a series is determined by the function Sn =
a1(rn)−a1/r-1
Sigma notation can be used to find the sum of a sequence with a given number of terms. The Greek symbol Σ can be used with a lower index and upper index to indicate which terms of the sequence to add together.
