Let the first number be x, then the second number is 2x, the third number is %28x%2B100%29
The sum of these three numbers is x%2B2x%2B%28x%2B100%29
x%2B2x%2Bx%2B100=336
4x=336-100
4x=236
x=236%2F4
x=59
The first number is 59, the second number is 2%2A59=118, the third number is 59%2B100=159
Answer: 59, 118, 159
