The road to Rome

fr_img052
Moving from one box to the following: * By multiplying by 2 if you move to the right; * Add 1 if you move down. It can go either up or left. We go of Paris with 1 and runs through all possible paths from Paris to Rome. What is the sum of all numbers obtained in Rome?

    excuse me you can’t go up or left
    and can you explain your result ?

  3. Josephine says

    I go from Paris, then right and then down.
    Like:
    1 +1 * 2 * 2 * 2 *2 = 17
    1 * 2 + 1 * 2 * 2 * 2 = 10
    1 * 2 * 2 +1 * 2 * 2 = 8
    1 * 2 * 2 * 2 + 1 * 2 = 10
    1 * 2 * 2 * 2 * 2 + 1 = 17

    So when I come to Rome it must be
    17 + 10 + 8 + 10 + 17 = 62
    Right?
