Math Problem Statement

the sum of 4 consecutive integers is -106

Solution

Let the four consecutive integers be represented as xx, x+1x+1, x+2x+2, and x+3x+3.

The sum of these integers is given by:

x+(x+1)+(x+2)+(x+3)=106x + (x+1) + (x+2) + (x+3) = -106

Simplifying the left-hand side:

4x+6=1064x + 6 = -106

Now, subtract 6 from both sides:

4x=10664x = -106 - 6 4x=1124x = -112

Next, divide both sides by 4:

x=1124=28x = \frac{-112}{4} = -28

So, the first integer is x=28x = -28.

The four consecutive integers are:

28,27,26,25-28, -27, -26, -25

Finally, we can check the sum:

28+(27)+(26)+(25)=106-28 + (-27) + (-26) + (-25) = -106

Thus, the solution is correct.
