Investigations 8 Easy Steps1. Situation

You will normally be given a description of what’s going on, for example, a pattern that you can continue.

2. Generate data

You have to continue the pattern.

3. Organise the data

You usually put your data into a table.

4. Analyse the data

Determine how the pattern is growing. If it's a sequence, you should begin by looking at first differences. If that doesn’t work, compare the numbers to sequences you know. You may have to manipulate the numbers (add 1 or 2 to them, subtract 1 or 2, double them, etc.)

5. Find a rule / formula / expression for the nth term.

Use your knowledge of sequences to find a formula (a common first difference is the coefficient in a linear sequence, etc.)

6. Test the rule

Use the pattern and the rule to get the same value for the next term.

7. Prove the rule

Use algebra or some other means to show the rule works for all values of n.

8. Extension

Think of ways you can explore further.
