Hi, Sam.

 

Ok, so 3 consecutive numbers. Let's call them X, X + 1, X + 2

 

Now, if we add them, they equal 111.

 

X + X + 1 + X + 2 = 111

 

3X  + 3 = 111

3X = 108

X = 36

 

Now we have X so we can find the 3 numbers:

 

36, 37 and 38.

 

Let's check:

36 + 37 + 38 = 111

 

Yes, it works!
