Answer:
210, 211, 212
Step-by-step explanation:
If we denote the first number as x, then the second number can be written as x + 1 and the third number as x + 2.
The equation is:
x + (x + 1) + (x + 2) = 633
3x + 3 = 633
3x = 633 - 3
3x = 630
x = 210
So the three consecutive numbers we're looking for are: 210, 211, 212
