What three consecutive integers have a sum of 4311?

Here we will use algebra to find three consecutive integers whose sum is 4311. 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 4311. Therefore, you can write the equation as follows:

(X) + (X + 1) + (X + 2) = 4311

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 = 4311
3X + 3 = 4311

3X + 3 - 3 = 4311 - 3
3X = 4308

3X/3 = 4308/3
X = 1436

Which means that the first number is 1436, the second number is 1436 + 1 and the third number is 1436 + 2. Therefore, three consecutive integers that add up to 4311 are 1436, 1437, and 1438.

1436 + 1437 + 1438 = 4311

We know our answer is correct because 1436 + 1437 + 1438 equals 4311 as displayed above.
