Answer:

Step-by-step explanation:

Each term in the sequence is 4 less than the previous term. That indicates an arithmetic sequence, which has the form a(n) = a(1) + d(n -1), where d is the common difference. Here the common difference is -4, and so the appropriate sequence is

a(n) = 14 - 4(n - 1)
