Let the smallest number be x
The other two numbers are (x + 1) and (x + 2)
Solve x:
Sum of the 1st and 2nd is 3 more than the 3rd:
x + (x + 1) = (x + 3) + 3
x + x + 1 = x + 3 + 3
2x + 1 = x + 6
x = 5
Find the numbers:
1st number = x = 5
2nd number = x + 1 = 5 + 1 = 6
3rd number = x + 2 = 5 + 2 = 7
Answer: The numbers are 5, 6 an 7.
