What three consecutive integers have a sum of 6240?

Here we will use algebra to find three consecutive integers whose sum is 6240. 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 6240. Therefore, you can write the equation as follows:

(X) + (X + 1) + (X + 2) = 6240

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 = 6240
3X + 3 = 6240

3X + 3 - 3 = 6240 - 3
3X = 6237

3X/3 = 6237/3
X = 2079

Which means that the first number is 2079, the second number is 2079 + 1 and the third number is 2079 + 2. Therefore, three consecutive integers that add up to 6240 are 2079, 2080, and 2081.

2079 + 2080 + 2081 = 6240

We know our answer is correct because 2079 + 2080 + 2081 equals 6240 as displayed above.
