Answer:
1st number: 38
2nd number: 228
3rd number: 138
Explanation:
Lets call the first number x
The second number is 6x
The third number is x+100
x+6x+x+100=404
8x+100=404
8x=304
x=38
The first number is 38
The second number is 6(38), which is 228
The third number is 38+100, which is 138
38+138+220 = 404
