Answer:
d(n) = 85 * ( 3 - n )
Step-by-step explanation:
Let's find the common difference of the terms (if any).
The common difference is = 85 - 170 = 0 - 85 = -85 - 0 = -85
For an arithmatic sequence with first term a, common difference d,
nth term = a + ( n - 1 ) * d
So, d(n) = 170 + ( n - 1 ) * (-85)
= 255 - 85n
= 85 ( 3 - n )
