Answer: 138
Explanation:
Let the first number be x , the second number be x + 2 and the third number be x + 4 since they are consecutive even numbers.
Their sum implies:
x + x + 2 + x + 4 = 408
3x + 6 = 408
subtract 6 from both sides
3x + 6 - 6 = 408 - 6
3x = 402
divide through by 3
3x/3 = 402/3
Therefore x = 134.
The numbers are :
134 , 136 and 138 , this means that the largest number is 138
