a father is four times as old as his son. in 4 years, the father will be three times as old as the son. how old is each now?

I believe

Father= 40

Son=10

I researched this and it’s really confusing. I’m not sure how to explain it to you, but I might be able to send you screenshots of what I’ve seen if you would like. If this is wrong please let me know. I hope this helps!!

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.
