Answer:

-82, -83, -84

Step-by-step explanation:

Using a variable and corresponding expressions, we can set the sum of the consecutive integers equal to -249 and solve:

first integer: x

second integer: x + 1

third integer: x + 2

x + x + 1 + x + 2 = -249

Combine like terms: 3x + 3 = -249

Subtract 3 from both sides: 3x + 3 - 3 = -249 - 3  or 3x = -252

Divide both sides by 3: 3x/3 = -252/3

Solve for x: x = -84

first integer: -84

second integer: -84 + 1 = -83

third integer: -84 + 2 = -82
