Often, people make predictions about what will happen next based on what has happened so far. They begin by looking for a pattern in what has happened and use this pattern to predict what will happen next.

For instance, if you type 30 words in one minute and 60 words in two minutes, you might notice that for every minute that goes by, you can type 30 more words. So, for three minutes, you might predict that you will type 90 words (30 + 30 + 30) in three minutes. You are making a prediction about what will happen next (90 words in three minutes) based on a pattern you found in what has happened so far (30 words in one minute and 60 words in two minutes).

In Algebra, we explore these predictions further to find a rule (an equation) that we can use to quickly determine what will happen at any time in the future. For instance, the rule for the typing situation above is:

The number of minutes times 30 = The number of words you type

1 minute x 30 = 30 words

2 minutes x 30 = 60 words

3 minutes x 30 = 90 words

100 minutes x 30 = 3000 words
