Let's call the first number x.
Then the three consecutive numbers would be x, x+1, and x+2.
According to the problem, the sum of these three numbers is 57.
So, we can write the equation as:
x + (x+1) + (x+2) = 57
Simplifying the equation, we have:
3x + 3 = 57
Subtracting 3 from both sides, we get:
3x = 54
Dividing both sides by 3, we find:
x = 18
Therefore, the largest of these three numbers is x+2, which is 18 + 2 = 20.
So, the answer is 20.
The sum of three consecutive numbers is 57. What is the largest of these numbers?
