You can use 101 bags.
Have one bag be empty. Put it aside somwhere.
Put one marble in the second bag.
Put the second bag into the third bag, then put a second marble into the third bag (but outside the second bag) - there are now 2 marbles in the third bag.
Put the third bag into the fourth bag, and add a third marble - the fourth bag now has 3.
Repeat with 100 bags and 100 marbles. Plus you have one empty one. |
