Answer 3

Let's assume the three consecutive numbers are x, x+1, and x+2.

According to the problem, the sum of these three numbers is 168:

x + (x+1) + (x+2) = 168

Now, let's solve this equation to find the value of x (the first number):

Combine like terms:

3x + 3 = 168

Subtract 3 from both sides:

3x = 165

Now, divide both sides by 3 to isolate x:

x = 165 / 3

x = 55

Now that we have found the value of x (the first number), we can find the second number (x+1):

Second number = 55 + 1 = 56

So, the second number is 56.
