The problem states:

Find 4 consecutive whole numbers such that the sum of the first three numbers equals the fourth number.

Ok, so heres how I think it should be:

x = 1st #

x+1 = 2nd #

x+2 = 3rd #

x+3 = 4th #

(x) + (x+1) + (x+2) = (x+3)

Now if this is correct then this is how it works out...

3x+3=x+3

2x+3=3

2x=0

Now this is where Im stumped. Any help would be appreciated.
