Moving from one box to the following:
* By multiplying by 2 if you move to the right;
* 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?
the sum when you end in Rome is 62
excuse me you can’t go up or left
and can you explain your result ?
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?
yes you right, congratulation 🙂
