She finished by climbing a tree that was 200 feet taller than her first tree.  What was the average height of the trees that Jackie climbed?

conversations.value: Jackie climbed 2 trees that were 1/2 * 1000 feet = 500 feet tall each.
  Jackie climbed a final tree that was 1000 + 200 feet = 1200 feet.
  In total, the 4 trees Jackie climbed were 1000 feet + 500 feet + 500 feet + 1200 feet = 3200 feet.
  The average height tree that Jackie climbed was 3200 feet / 4 trees = 800 feet tall.
