Question 323819: what 3 numbers are consecutive numbers equal 15,000
Answer by rapaljer(4671)   (Show Source):
You can put this solution on YOUR website! The traditional way to solve this problem is to say,
Let x= first number
x+1= second number
x+2= third number
The equation is
x+x+1+x+2= 15000
3x+3=15000
3x=14997
x=4999
x+1=5000
x+2=5001
HOWEVER, the non-traditional way to solve this is to recognize that if the sum of three consecutive numbers is 15,000, the AVERAGE of the numbers is 5,000. The other two numbers are on either side of this: 4999, 5000, and 5001.
