Remark
What you have to do to learn the difference between recursive and explicit is try try the first 3 or 4 terms to see what you have and how you did it.
a1 = - 3
a2 = - 3 (1/8) = -3 / 8
a3 = (a2) (1/8)
a3 = (-3/8) * 1/8
a3 = (- 3/64)
a4 = a3 (1/8)
a4 = -3/64 * 1/8
a4 = - 3 / 512
Take a good look at a4. What do you notice? No matter what, you are always multiplying by 1/8. That means that A and D are both wrong which they would have you raising by 3 or - 3 to some power.
So which one of B and C is correct?
The answer is which ever one will not change sign from what it started out with. All four terms are minus.
In B the term is multiplied by plus 1/8. That will not change the sign of the next term.
So the answer is
a_n = - 3 * (1/8)^(n - 1) <<<<< answer
C
I-12-(-15)l
l-12+15l
l3l = 3
Problem
Solution
If we look the graph careful we can see that the angle C is equivalent to the angle G
so then the best answer would be :
G
9514 1404 393
Answer:
pieces of candy = 16 × boxes of candy
Step-by-step explanation:
Each "pieces" number is 16 times the corresponding "boxes" number, so we can write ...
pieces of candy = 16 × boxes of candy
__
If you like, you can assign variables. Let x = boxes of candy, and y = pieces of candy. Then you have ...
y = 16x
