Problem
To find the 20th term of the sequence: 7, 12, 17, 22.
The rule for the nth term of the sequence is addding 5 to the term before to get the next term.
Concept
This is an arithmetic sequence since there is a common difference between each term. In this case .
Common ratio = 5
The term to term rule of a sequence describes how to get from one term to the next.
Final answer
The first term is 7. The term to term rule is 'add 5'.
