After completing this tutorial, you will be able to complete the following:

- Describe the general rule for input/output tables.
- Write the general rule for input/output tables in algebraic notation.

There is a relationship between the inputs and outputs.

In this Activity Object, students must find the relationship between inputs and outputs to find a pattern (or general rule) that can be described by an algebraic equation.

In the example below, the pattern suggests that the input value should be multiplied by 2 to get the output value.

General rule: Output = Input × 2

Using the above chart, the general rule can be written with variables. For example, let m represent the output and n the input. Then the algebraic equation becomes:

m = n × 2

After writing the general rule, one should always check if the equation is correct by inserting the values of inputs into the equation.
