Here we will use algebra to find three consecutive integers whose sum is 474. 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 474. Therefore, you can write the equation as follows:
(X) + (X + 1) + (X + 2) = 474
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 = 474
3X + 3 = 474
3X + 3 - 3 = 474 - 3
3X = 471
3X/3 = 471/3
X = 157
Which means that the first number is 157, the second number is 157 + 1 and the third number is 157 + 2. Therefore, three consecutive integers that add up to 474 are 157, 158, and 159.
157 + 158 + 159 = 474
We know our answer is correct because 157 + 158 + 159 equals 474 as displayed above.
