Hey there,

Here is a test to how good your math is...

I decided to do it again.
Being consecutive even numbers, we need to add 2 to the previous number.
Assign variables :
Let x = first consecutive even
Let x + 2 = second consecutive even
Let x + 4 = third consecutive even
4x = 6 + 2(x+4)
4x = 6 + 2x + 8
4x = 2x + 14
4x - 2x = 14

2x = 14
x = 14/2
x = 7
The numbers are 7, 9, and 11.
As you can see, the numbers are odd not even. There could be a typo in your original question. There is no way we can get three consecutive even integers from this question. We get three consecutive odd integers.

Hi ,

Let x , ( x + 2 ) and ( x + 4 ) are three

consecutive even numbers ,

According to the problem given ,

4 times of first number = product of 2

and third number + 6

4x = 2(x + 4 ) + 6

4x = 2x + 8 +6

4x - 2x = 14

2x = 14

x = 14/2

x = 7

Therefore ,

Required even numbers are ,

x = 7 ;

x + 2 = 7 + 2 = 9 ;

x + 4 = 7 + 4 = 11 :

I hope this helps you.
