The sum of three numbers is 29. The second number is three times the first number, and the third number is four more than the first number. What are the three numbers?

Answer 1

n = first number

3n = second number

n + 4 = third number

n + 3n + (n + 4) = 29

5n + 4 = 29

n = (29 - 4) / 5 = 5

The numbers are 5, 15, and 9.
