What three consecutive integers have a sum of 807?

Here we will use algebra to find three consecutive integers whose sum is 807. We start by assigning X to the first integer. Since they are consecutive, it means that the 2nd number will be X + 1 and the 3rd number will be X + 2 and they should all add up to 807. Therefore, you can write the equation as follows:

(X) + (X + 1) + (X + 2) = 807

To solve for X, you first add the integers together and the X variables together. Then you subtract three from each side, followed by dividing by 3 on each side. Here is the work to show our math:

X + X + 1 + X + 2 = 807
3X + 3 = 807

3X + 3 - 3 = 807 - 3
3X = 804

3X/3 = 804/3
X = 268

Which means that the first number is 268, the second number is 268 + 1 and the third number is 268 + 2. Therefore, three consecutive integers that add up to 807 are 268, 269, and 270.

268 + 269 + 270 = 807

We know our answer is correct because 268 + 269 + 270 equals 807 as displayed above.
