What three consecutive integers have a sum of 2538?

Here we will use algebra to find three consecutive integers whose sum is 2538. 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 2538. Therefore, you can write the equation as follows:

(X) + (X + 1) + (X + 2) = 2538

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 = 2538
3X + 3 = 2538

3X + 3 - 3 = 2538 - 3
3X = 2535

3X/3 = 2535/3
X = 845

Which means that the first number is 845, the second number is 845 + 1 and the third number is 845 + 2. Therefore, three consecutive integers that add up to 2538 are 845, 846, and 847.

845 + 846 + 847 = 2538

We know our answer is correct because 845 + 846 + 847 equals 2538 as displayed above.
