Answer 2

Given :-

The sum of three consecutive numbers = 57

To Find :-

The largest of these numbers.

Analysis :-

Firstly, consider the three consecutive numbers as variables added to integers one after the other.

Make an equation accordingly.

Get the value of the variable and substitute them on the other numbers too.

Solution :-

Let the three consecutive numbers be x, x+1 and x+2 respectively.

Given that,

The sum of three consecutive numbers = 57

Making their equation,

x + x + 1 + x + 2 = 57

3x + 3 = 57

By transposing 3,

3x = 57 - 3

3x = 54

Finding x,

x = 54/3

x = 18

Finding other numbers,

x + 1 = 18 + 1 = 19

x + 2 = 18 + 2 = 20

Therefore, the largest of these numbers is (c) 20.
