What three consecutive integers have a sum of 3866?

Here we will use algebra to find three consecutive integers whose sum is 3866. 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 3866. Therefore, you can write the equation as follows:

(X) + (X + 1) + (X + 2) = 3866

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 = 3866
3X + 3 = 3866

3X + 3 - 3 = 3866 - 3
3X = 3863

3X/3 = 3863/3
X = 1287 2/3

Since 1287 2/3 is not an integer, there is no true answer to this problem.

However, there are three numbers that add up to 3866. The first number is (1287 2/3), the second number is (1287 2/3) + 1, and the third number is (1287 2/3) + 2. Therefore, we could make this the answer to "Three consecutive numbers that add up to 3866 are?":

1287 2/3 + 1288 2/3 + 1289 2/3 = 3866
