Answer:
ay = 39 -6(n -1)
Step-by-step explanation:
The explicit formula for an arithmetic sequence can be written by using the first-term value and the common difference in the generic formula.
__
The generic formula for the n-th term of an arithmetic sequence is ...
[tex]a_n=a_1+d(n-1)[/tex]
where a₁ is the first term of the sequence (39), and d is the difference between sequential terms (33-39 = -6).
Using the values for this sequence in the generic formula, we have ...
ay = 39 -6(n -1)
