What three consecutive integers have a sum of 8865?

Here we will use algebra to find three consecutive integers whose sum is 8865. 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 8865. Therefore, you can write the equation as follows:

(X) + (X + 1) + (X + 2) = 8865

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 = 8865
3X + 3 = 8865

3X + 3 - 3 = 8865 - 3
3X = 8862

3X/3 = 8862/3
X = 2954

Which means that the first number is 2954, the second number is 2954 + 1 and the third number is 2954 + 2. Therefore, three consecutive integers that add up to 8865 are 2954, 2955, and 2956.

2954 + 2955 + 2956 = 8865

We know our answer is correct because 2954 + 2955 + 2956 equals 8865 as displayed above.
