Answer: 3n+1
(no need to type in the "a_n" or "an" part, as it's already done)

Explanation:
The first term is a1 = 4 since it is given to us
The common difference is d = 3. This is the value that we add to each term to get the next as the recursive steps shows when we write a(n) = a(n-1)+3
In other words,
nth term = [ (n-1)st term ] + 3
next term = (previous term) + 3
Using a1 = 4 and d = 3, we get the following
an = a1+d(n-1)
an = 4 + 3(n-1)
an = 4+3n-3
an = 3n + (4-3)
an = 3n+1
There's 53 boxes on Friday, and 27 boxes on Saturday, which means that there's 80 boxes in total.
53+27=80
Since there is 10 oranges in each box, there is 800 oranges in total.
80 boxes*10 oranges=800 oranges
Hmm, I think you would take 40 and multiply it by 2 because her sister used "twice as many". Then I'm pretty sure you would take your answer from that and divide it by 2 because she used that amount of paper in "half the number of days"?
40 x 2 = 80 all together used
80 / 2 = 40 how many used each day
Is that what you were asking? If I'm wrong let me know please
Is there a picture to that question
