What three consecutive integers have a sum of 4449?

Here we will use algebra to find three consecutive integers whose sum is 4449. 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 4449. Therefore, you can write the equation as follows:

(X) + (X + 1) + (X + 2) = 4449

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 = 4449
3X + 3 = 4449

3X + 3 - 3 = 4449 - 3
3X = 4446

3X/3 = 4446/3
X = 1482

Which means that the first number is 1482, the second number is 1482 + 1 and the third number is 1482 + 2. Therefore, three consecutive integers that add up to 4449 are 1482, 1483, and 1484.

1482 + 1483 + 1484 = 4449

We know our answer is correct because 1482 + 1483 + 1484 equals 4449 as displayed above.
