Connecting Averages Kimaya

Answer- My method is to count how much there is on any side. So, add the least no. needed to make the total a multiple of 4. Then write the average and try it for the other side. If it works try for the middle. If not then start over using the next possible multiple of 4. If the total of the middle and the average doesn’t work then start over using the next possible multiple of 4. If it works then the puzzle is solved.
