What three consecutive integers have a sum of 6?

Here we will use algebra to find three consecutive integers whose sum is 6. 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 6. Therefore, you can write the equation as follows:

(X) + (X + 1) + (X + 2) = 6

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 = 6
3X + 3 = 6

3X + 3 - 3 = 6 - 3
3X = 3

3X/3 = 3/3
X = 1

Which means that the first number is 1, the second number is 1 + 1 and the third number is 1 + 2. Therefore, three consecutive integers that add up to 6 are 1, 2, and 3.

1 + 2 + 3 = 6

We know our answer is correct because 1 + 2 + 3 equals 6 as displayed above.
