What three consecutive integers have a sum of 1398?

Here we will use algebra to find three consecutive integers whose sum is 1398. 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 1398. Therefore, you can write the equation as follows:

(X) + (X + 1) + (X + 2) = 1398

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 = 1398
3X + 3 = 1398

3X + 3 - 3 = 1398 - 3
3X = 1395

3X/3 = 1395/3
X = 465

Which means that the first number is 465, the second number is 465 + 1 and the third number is 465 + 2. Therefore, three consecutive integers that add up to 1398 are 465, 466, and 467.

465 + 466 + 467 = 1398

We know our answer is correct because 465 + 466 + 467 equals 1398 as displayed above.
