Find three consecutive number whose sum is 438

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
