What three consecutive integers have a sum of 3447?

Here we will use algebra to find three consecutive integers whose sum is 3447. 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 3447. Therefore, you can write the equation as follows:

(X) + (X + 1) + (X + 2) = 3447

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 = 3447
3X + 3 = 3447

3X + 3 - 3 = 3447 - 3
3X = 3444

3X/3 = 3444/3
X = 1148

Which means that the first number is 1148, the second number is 1148 + 1 and the third number is 1148 + 2. Therefore, three consecutive integers that add up to 3447 are 1148, 1149, and 1150.

1148 + 1149 + 1150 = 3447

We know our answer is correct because 1148 + 1149 + 1150 equals 3447 as displayed above.
