The sum of three consecutive whole numbers is 18. what is the greatest of the numbers?

7 is the greatest number

Step-by-step explanation:

We need to consider that our first number is X

This means that the second number is X+1 and the third number is x+2

If we add all the numbers we get

x + x+1 + x+ 2 = 18   (Since the sum must be 18)

We get

3x + 3 = 18   (We substract 3 on both sides)

3x +3 - 3 = 18 - 3

3x = 15  (We divide by 3 on both sides)

x= 5  (This is the smallest number)

The numbers are 5, 6 and 7. The greatest is 7.
