Question: Luke has blue and red balls.
Every day, he wins 2 blue balls and loses 3 red ones
After 5 days, he has the same amount of blue and re
After 9 days, he has twice as many blue balls as rec
How many red balls did he have at the beginning?

The number of red balls, in the beginning, is 47.

Step-by-step explanation:

According to the question,

Should let the number of blue balls will be "x" in the beginning and indeed the number of red balls will be "y".

After five days,

⇒   ...(equation 1)

After nine days,

⇒   ...(equation 2)

On applying subtraction between the above two equations, we get

⇒  

⇒  

y = 2x

step-by-step explanation:

if you divide each number in the sequence, you'll see that they all have a multiple factor of 2. each number in the series, and any other numbers which may continue, will be multiplied by 2. therefore, y is the next number in the sequence, and x is the current one, so, our formula will be y = 2x.
