Question

Find three consecutive even numbers whose sum is 54

Answer 1

answer :
       Let the three consecutive even numbers be x , x+2 and x+4 .
 
         Sum of three consecutive even  numbers = 54
         x  + (x+2)  +  (x+4) = 54
        3x + 6  = 54
         3x = 54 - 6
         3x = 48
         or x = 48/3
           or x = 16
       therefore x+2 = 16 + 2 = 18
                   and x+4 = 16 +4 = 20
     hence three conscutive even numbers are 16 , 18 and 20 .

Answer 2

Answer:

Here is your solution

Let,

The first even integer be:x

Then the second even integer is:x+2

Then the third even integer is: x+2+2=x+4

Sum of three consecutive even numbers =54

A/q

(x)+(x+2)+(x+4)=54

3x+6=54

3x=54-6

3x=48

x=16

now

The first integer is:x=16

the second integer is:x+2=16+2=18

the third integer is: x+4=16+4=20
