Answer:
Step-by-step explanation:
Notice that each new term in the arithmetic sequence 1, -1, -3, ... is 2 less than the previous term. Thus, the common difference is -2.
The formula for this sequence is a(n) = 1 - 2(n - 1), or a(n) = 3 - 2n
Let the weights of the two candies be repres. by x and y.
Then x + y = 60, or x = 60 - y
($1.16 / lb) x + ($0.86 / lb) y = ($1.00 / lb) (60 lb) = $60
Then 1.16(60-y) + 0.86y = 60
69.6 - 1.16y + 0.86y = 60 9.6
9.6 = 0.3y Solving for y, y = ------- = 32 lb
0.3
Then x = (60-32) lb = 28 lb
