Answer:
a(66) = -1133
Step-by-step explanation:
The common difference here is -17. Note that -45 is equal to the previous value (-28), and that subtracting 17 from -28 yields -45.
Then the explicit equation of this arithmetic sequence is
a(n) = -28 - 17(n - 1)
and the 66th term is a(66) = -28 - 17(65), or a(66) = -1133
