What three consecutive integers have a sum of 1647?

Here we will use algebra to find three consecutive integers whose sum is 1647. 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 1647. Therefore, you can write the equation as follows:

(X) + (X + 1) + (X + 2) = 1647

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 = 1647
3X + 3 = 1647

3X + 3 - 3 = 1647 - 3
3X = 1644

3X/3 = 1644/3
X = 548

Which means that the first number is 548, the second number is 548 + 1 and the third number is 548 + 2. Therefore, three consecutive integers that add up to 1647 are 548, 549, and 550.

548 + 549 + 550 = 1647

We know our answer is correct because 548 + 549 + 550 equals 1647 as displayed above.
