What three consecutive numbers add up to 93? Is there a method to find them?

To solve this, assume that the three consecutive numbers are all integers. Then, assign a variable that represents the first integer.  Let it be x.  So the next two integers are x+1 and x+2.


Then, add these three integers and set it equal to the given sum.



And solve for x.







This is the first integer. The other two integers are:


second integer
