Question

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

Answer 1

Let the three even consecutive number be x, x+2,x+4
According to the question,
x+x+2+x+4 = 54
3x+6 = 54
3x = 48
x = 16
x+2=18
x+4=20
The three consecutive numbers are 16,18,20

Answer 2

Heya,

Ur answer is here.

Let the first number be x.

Then, the second number will be x+2

The third number will be x + 2 + 2 = x + 4.

Now, It is given that the sum of all three numbers is 54.

So, 
x + (x+2) + (x+4) = 54.
3x + 6 = 54
3x = 48

Hence, x = 16.
Second Number = x + 2 = 18.
Third Number = x + 4 = 20.

Hence, the three even numbers whose sum is 54 are 16, 18 and 20.

Hope it helps
