The sum of 3 consecutive integers is 90. Find the largest integer if x is the smallest integer.

31

Step-by-step explanation:

Note that it is given that the three integers are consecutive, meaning that when represented by x, you have 3 integers: x, x+1, and x+2.

Then you use the fact that the sum of the three integers is 90:

         x + x+1 + x+2 = 90

         3x + 3 = 90

         3x = 87

         x = 29

Now notice that the question is asking for the largest integer, not x. So the answer is 31.
