Question 186292: Write an equation to find the three consecutive numbers that equal 63

You can put this solution on YOUR website! Write an equation to find the three consecutive numbers that equal 63
-----------------------
If x is the smallest number, then
x + x+1 + x+2 = 63
3x+3 = 63 This is what was asked for. If you want to solve it:
--------------
3x+3 = 63
3x = 60
x = 20
The numbers are 20, 21 and 22
---------------
A quicker way to do this (you might have a timed test) is to divide 63 by to get the average. The average is the middle number.
63/3 = 21
--> 21, 21 & 22 (in a lot less time)
