Question 814617: 1250 oranges were distributed among a group of girls of a class. Each girl got twice as many oranges as the number of girls in that group. The number of girls in the group was- Answer by LinnW(1048) (Show Source):
You can put this solution on YOUR website! Let's develop a sequence that describes what happens
as group size increases.
For a group of 2 we get 2(2(2)), that is each of the two girls in
the group gets 2*2 oranges.
For a group of 3 we get 3(2(3)).
So a particular element of our sequence will be n(2n) were n is a positive integer.
Consider the equation n(2n) = 1250. Solving for n should give us the group size.
n(2n) = 1250
Divide each side by 2
Take the square root of each side and we have
n = 25.
