Here is an example of a problem that can be solve using a table and a pattern:

Alice needs `3` gal of water to water a plant. How many gallons of water will she need for `30` plants?

We know that for 1 plant Alice need `3` gal of water, therefore for `2` plants, Alice will be needing `3 ` `*2` gal` = 6` gal of water. Then, for `3` plants she will be needing` 3` `* 3` gal `= 9` gal of water, and for `4 ` plants that will require her to have` 4 * 3` gal `= 12 ` gal of water. Creating a table for the number of plants and the number of gallons she will need, will give us:

Number of plants Number of gallons of water

1 3

2 6

3 9

4 12

5 15

6 18

7 21

8 24

9 27

10 30

Therefore, **Alice needs 30 gal of water for 10 plants**.

That is it! :)
