Step-by-step explanation:
Let x be the first number
Consecutive means in a row
x+1 is the second number
x+2 is the third number
x + x+1 + x+2 = 45
Combine like terms
3x+3 = 45
Subtract 3 from each side
3x+3-3=45-3
3x = 42
Divide each side by 3
3x/3 = 42/3
x = 14
The first number is 14
The second number is 14+1 = 15
The third number is 14+2 = 16
