The tree that grows

The tree that grows

A new species of tropical tree has been discovered that doubles its height every year until it reaches its maximum height after 10 years.

How many years will it take the tree to reach half its height?

Solution

We know that every year it doubles its height so that one year before the 10 in which the tree grows it will be half the height, this is 9 years.

By the way, if you look closely you will see that the tree looks like a dancing dancer.
