First number: x
Second number: x + 1
Third number: x + 2
Sum of the three consecutive numbers = 63
Equation:
(x) + (x + 1) + (x + 2) = 63
3x + 3 = 63
3x = 63 - 3
3x/3 = 60
x = 20
The three consecutive numbers are:
First number: x = 20
Second number: x + 1 = 20 + 1 = 21
Third number: x + 2 = 20 + 2 = 22
The three consecutive numbers are 20, 21, 22.
Check:
20 + 21 + 22 = 63
41 + 22 = 62
63 = 63
