The sum of three consecutive numbers is 42. What are the three numbers?

13,14,15

Step-by-step explanation:

Let x be the first number

x+1 is the second number

x+2 = third number

x + x+1 + x+2 = 42

Combine like terms

3x+3 = 42

Subtract 3 from each side

3x+3-3 = 42-3

3x = 39

Divide each side by 3

3x/3 = 39/3

x = 13

The numbers are 13

13+1 = 14

13+2 = 15

13,14,15

Step-by-step explanation:

What three consecutive integers have a sum of 42? Which means that the first number is 13, the second number is 13 + 1 and the third number is 13 + 2. Therefore, three consecutive integers that add up to 42 are 13, 14, and 15.
