Answer:

Step-by-step explanation:
Given:
Gisselle has 1/2 of a candy bar.
She role off 1/2 of what she had and split it into three equal pieces.
Question asked:
What fraction of a candy bar was each piece?
Solution:
Gisselle has = 
She role off = 

As she split it into three equal pieces, we will divided it by 3, we get,


Therefore, fraction of a candy bar of each piece is 
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 )
