What three consecutive integers have a sum of 6456?

Here we will use algebra to find three consecutive integers whose sum is 6456. 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 6456. Therefore, you can write the equation as follows:

(X) + (X + 1) + (X + 2) = 6456

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 = 6456
3X + 3 = 6456

3X + 3 - 3 = 6456 - 3
3X = 6453

3X/3 = 6453/3
X = 2151

Which means that the first number is 2151, the second number is 2151 + 1 and the third number is 2151 + 2. Therefore, three consecutive integers that add up to 6456 are 2151, 2152, and 2153.

2151 + 2152 + 2153 = 6456

We know our answer is correct because 2151 + 2152 + 2153 equals 6456 as displayed above.
