To find the 17th term of the sequence, we need to first determine the common difference (d) and the first term (a1).
Given that a18 = -7 and d = -5, we can find a1 using the formula:
a18 = a1 + (18-1)(-5)
-7 = a1 - 85
a1 = -7 + 85
a1 = 78
Now that we have a1 and d, we can find the 17th term using the formula:
a17 = a1 + (17-1)(-5)
a17 = 78 + 16(-5)
a17 = 78 - 80
a17 = -2
Therefore, the 17th term of the sequence is -2.
