What three consecutive integers have a sum of 4230?

Here we will use algebra to find three consecutive integers whose sum is 4230. 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 4230. Therefore, you can write the equation as follows:

(X) + (X + 1) + (X + 2) = 4230

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 = 4230
3X + 3 = 4230

3X + 3 - 3 = 4230 - 3
3X = 4227

3X/3 = 4227/3
X = 1409

Which means that the first number is 1409, the second number is 1409 + 1 and the third number is 1409 + 2. Therefore, three consecutive integers that add up to 4230 are 1409, 1410, and 1411.

1409 + 1410 + 1411 = 4230

We know our answer is correct because 1409 + 1410 + 1411 equals 4230 as displayed above.
