What three consecutive integers have a sum of 5280?

Here we will use algebra to find three consecutive integers whose sum is 5280. 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 5280. Therefore, you can write the equation as follows:

(X) + (X + 1) + (X + 2) = 5280

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 = 5280
3X + 3 = 5280

3X + 3 - 3 = 5280 - 3
3X = 5277

3X/3 = 5277/3
X = 1759

Which means that the first number is 1759, the second number is 1759 + 1 and the third number is 1759 + 2. Therefore, three consecutive integers that add up to 5280 are 1759, 1760, and 1761.

1759 + 1760 + 1761 = 5280

We know our answer is correct because 1759 + 1760 + 1761 equals 5280 as displayed above.
