What three consecutive integers have a sum of 1377?

Here we will use algebra to find three consecutive integers whose sum is 1377. 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 1377. Therefore, you can write the equation as follows:

(X) + (X + 1) + (X + 2) = 1377

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 = 1377
3X + 3 = 1377

3X + 3 - 3 = 1377 - 3
3X = 1374

3X/3 = 1374/3
X = 458

Which means that the first number is 458, the second number is 458 + 1 and the third number is 458 + 2. Therefore, three consecutive integers that add up to 1377 are 458, 459, and 460.

458 + 459 + 460 = 1377

We know our answer is correct because 458 + 459 + 460 equals 1377 as displayed above.
