Daily Practice – 04/09

The numbers – 8, 10, 12, 15 and 18 are rearranged according to these rules:

  1. The median isn’t first or last
  2. The largest isn’t first, but it is in one of the first three places
  3. The smallest isn’t last, but it is in one of the last three places

What is the average of the first and last numbers?
