Question

the sum of three consecutive even numbers is 54 find the numbers

Answer 1

Let the three consecutive even numbers be x-2 , x & x+2

Now, 
        x+2 + x + x-2 = 54
        3x = 54
        x = 18
So the nos. are
               x+2 = 20         x=18        x-2=16
CHECK:  16 + 18 + 20 =54
THANKS!

Answer 2

Hi there!
The numbers are consecutive even integers

Let the First no. be = x

Second no. be = x + 2

Third no. be = x + 4

ATQ,
Sum of all three consecutive even numbers is 54.

x + x + 2 + x + 4 = 54

3x + 6 = 54

x + 2 = 18

x = 18 - 2 = 16


Therefore,
The first no. is x = 16

Second no. is x + 2 = 16 + 2 = 18

Third no. is x + 4 = 16 + 4 = 20

♦ Verification :

16 + 18 + 20 = 54 [ VERIFIED. ]
