You will describe the general rule of a number sequence and write this rule in algebraic notation.
After completing this tutorial, you will be able to complete the following:
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.
