This is an arithmetic sequence because we are adding the same amount each time. In this case, we are adding -4 to each term to get the next term
17 + (-4) = 13
13 + (-4) = 9
9 + (-4) = 5
and so on. The starting term is 
The common difference is 
The nth term of the arithmetic sequence can be found by this formula

For instance, if n = 2, then,

which matches up with the second term listed.
Answer:

Step-by-step explanation:
