We worked on the first three questions:

We thought of how we could make the four numbers add up to a multiple of 4 and used trial and error. 

  1. 11, 5, 5
  2. 5, 6, 10, 5
  3. 5, 8, 12, 25, 70

For the third question, we actually worked from right to left because 243 was a large number and every missing number affected the next missing number.
