Answer: 10</h3>
=====================================================
Work Shown:
Plug in n = 1 to find the next term
f(n+1) = f(n) - 2
f(1+1) = f(1) - 2 ... replace every n with 1
f(2) = f(1) - 2
f(2) = 18-2 .... replace f(1) with 18
f(2) = 16
We'll use this to get the next term. Plug in n = 2
f(n+1) = f(n) - 2
f(2+1) = f(2) - 2 ... replace every n with 2
f(3) = f(2) - 2
f(3) = 16 - 2 ... replace f(2) with 16
f(3) = 14
This process keeps going until we reach f(5)
Plug in n = 3
f(n+1) = f(n) - 2
f(3+1) = f(3) - 2
f(4) = f(3) - 2
f(4) = 14-2
f(4) = 12
and finally plug in n = 4
f(n+1) = f(n) - 2
f(4+1) = f(4) - 2
f(5) = f(4) - 2
f(5) = 12 - 2
f(5) = 10
The summary is basically we subtract 2 from each term to get the next term. The sequence is 18, 16, 14, 12, 10 which is arithmetic.
Answer:
acute
Step-by-step explanation:
This problem is very simple. Knowing that y=2, plug 2 into the "y" in the equation: -x+2(2)=8
-x+4=8
subtract 4 on both sides of the equation:
-x=(8-4)
-x=4
Divide both sides of the equation by (-1):
x=(-4)

Answer: 1. You can use unit price to find how much one collar costs from each store to find which store is cheapest. 2. Just Dogs 3. 68 collars 4. 84 collars.
Step-by-step explanation:
Divide the number of dollars by the price to see what one collar costs from each store. Once you find out the cheapest collar and from which store that will be your answer for number 2. For number 3 multiple that price times 150. For the fourth question take 185 and divide it by the cheapest price collar to see how many you can get. If it turns out as a decimal anything behind the decimal point doesn't count. As you can't have 0.5 of a collar it's either 1 collar or no collar.
