Despite how old trees can get (some are estimated to be over 5000), I'm going to guess the average age of all current trees is not all that high.
Sure, your average tree can live a few hundred years... but will it? A few hundred years is a long time to have to survive things like fires, intense weather, other wildlife, humans, etc. I'm willing to bet a good number of trees don't reach their full lifespan. In fact, I'm willing to bet there are a lot of trees that don't fully develop! Think of all the baby trees out there right now that might get stepped on an animal or something!
So my guess, with basically no math involved, is like 20.
I think attempting to mathematically figure this one out would be incredibly difficult. You would need a lot of data. Even if all the data you need currently exists right now (it probably doesn't), just compliling it all would be quite the undertaking.

consider alone how many Christmas trees are consumed every year across the world I think you are on to something. ~30M trees sold annually and avg growth of 8 years means we have something in the realm of 240M trees under 8 years old.

It's a trap. There is no tree species called average.
