| Try making a table with the number of the square and the number
of grains of rice on that square, this way it may be easier to spot
a pattern. For example: |
| Square |
Number of grains of rice |
| 1 |
1 |
| 2 |
2
|
| 3 |
4 |
| 4 |
? |
| 5 |
? |
| 6 |
? |
|
Try to link the number in the left column to its related number
in the right column. Can you think of a general rule?
You may need to use powers. |
