Answer:
n(n+1)
Step-by-step explanation:
Only the last two formulas work for n=1; only the last formula works for n=2.
<u>For n=1</u>
3n = 3 ≠ 2
n² -1 = 0 ≠ 2
n² +1 = 2
n(n+1) = 2
<u>For n=2</u>
n²+1 = 5 ≠ 6
n(n+1) = 6 . . . . . this last formula works for the given sequence
1000milimeter=1meter
divide both sides by 1000
1mm=1/1000m
times both sides by 254
254mm=254/1000m
254mm=25.4/100m
254mm=2.54/10m
254mm=0.254/1m
254mm=0.254m
it is 0.254 meters
1. Car Mart sell 11 cars per day.
You can use the table by looking at day 2 and day 3. You can see underneath it, it shows how many cars is left after that particular day. So from day 2, you have 43 cars left and day 3, you got 32 cars left. From 43 car to 32 car is losing 11 car. So each day the Car Mart sell 11 car.
2. First we know that after 3 days, Winston have 32 cars left and after 5 day, it has 12 cars left.
Here’s the chart that I made for Winston:
Each day, Winston’s sell 10 cars. (Lose 10 cars per day)
