Sequences and Series
Question 1 of 8

1. How confident are you that you can explain:

a. sequences and series?


Example

A sequence is a list of numbers that can be generated by applying a rule. Here are two examples:

1, 3, 5, 7, 9,…
Rule: add two to the previous term to get the next term.

1, 4, 9, 16, 25,…
Rule: Square the position number; so the 4th term is found by squaring 4, the 6th term found by squaring 6, and so on.

A series is a sequence whose terms have been added.  For example:

1, 3, 5, 7,… is a sequence; 1 + 3 + 5 + 7 + … is a series.
