Let x = the smallest of the three consecutive integers.
Then x+1 = the middle-sized of the three consecutive integers.
Then x+2 = the largest of the three consecutive integers.










The largest integer less than  is 13.

So the three consecutive integers are 13,14,and 15. They add to 42.

Let smallest integer be S

Then others are: S + 1, and S + 2

The smallest INTEGER that's < 43 is 42

We then get: S + S + 1 + S + 2 = 42

3S + 3 = 42

3S = 39
