What three consecutive integers have a sum of 9390?

Here we will use algebra to find three consecutive integers whose sum is 9390. 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 9390. Therefore, you can write the equation as follows:

(X) + (X + 1) + (X + 2) = 9390

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 = 9390
3X + 3 = 9390

3X + 3 - 3 = 9390 - 3
3X = 9387

3X/3 = 9387/3
X = 3129

Which means that the first number is 3129, the second number is 3129 + 1 and the third number is 3129 + 2. Therefore, three consecutive integers that add up to 9390 are 3129, 3130, and 3131.

3129 + 3130 + 3131 = 9390

We know our answer is correct because 3129 + 3130 + 3131 equals 9390 as displayed above.
