Answer:

3126

Step-by-step explanation: f(1)=6 and f(n)=5f(n-1)-4. This means that next number is 5 times previous number minus 4.

f(2)=5f(1)-4 =5x6-4 = 30-4 = 26

f(3)=5f(2)-4 =5x26-4 = 130-4 = 126

f(4)=5f(3)-4 =5x126-4 = 630-4 = 626

f(5)=5f(4)-4 =5x626-4 = 3130-4 = 3126

The table shows the amount of sugar needed to make lemonade. Are the quantities proportional? Explain which method you used and
melomori [17]

Answer:

Yes, the quantities are proportional.

Step-by-step explanation:

To determine whether they were proportional or not, I compared the ratio of grams of sugar to servings in each pair of data points. 4/2, 6/3, 8/4, and 10/5 were the four points. All of them can be simplified to 2/1, which tells us that each serving of sugar is 2 grams, no matter how many servings are counted. This means that the amount of sugar grows in direct proportion to the number of servings.
