Answer:
145,146,147
Step-by-step explanation:
Let x be the first number
x+1 is the next number
x+1 +1 is the next number
The sum of these three number is
x + x+1 + (x+1+1) = 438
Combine like terms
3x +3 = 438
Subtract 3 from each side
3x+3-3 = 438-3
3x= 435
Divide by 3
3x/3=435/3
x = 145
x+1 =146
x+1+1 = 147
