17. The average attendance of a certain fitness class that meets daily for the first 4 days are given: 4,10,16,and 22 . Write a formula for the general term a_{n}that models the pattern.

Step 1 ：The given sequence is \([4, 10, 16, 22]\).

Step 2 ：This is an arithmetic sequence, where each term is obtained by adding a constant difference to the previous term.

Step 3 ：The common difference can be obtained by subtracting the first term from the second term, or the second term from the third term, and so on.

Step 4 ：In this case, the common difference is \(10 - 4 = 6\).

Step 5 ：Once we have the common difference, we can write the general term \(a_{n}\) of the sequence.

Step 6 ：The general term \(a_{n}\) of the sequence is given by \(a_{n} = 4 + (n-1)*6\).

Step 7 ：\(\boxed{a_{n} = 4 + 6(n-1)}\) is the final answer.
