Can you continue this sequence?!

2, 4, 6, 30, 32, 34, 36, 40, 42, 44, 46, ….

You will need to think outside the box for this one!

To identify an integer sequence try the **Online Encyclopedia of Integer Sequences**.

Simply type in your sequence and choose Search.

Note that you can list, graph or even listen to the sequence!

There are further links at the foot of the page, try **Puzzles** for some unusual sequences which includes the sequence above.

You can also use WolframAlpha, simply type in your the sequence, scroll down the page for **this example** and you will see a possible sequence identification.

**Typing Sequences into WolframAlpha** shows several possibilities for queries on sequences.

Several of the resources mentioned on the **notes** page include examples of sequences, see for example the **Math Centre resources on Sequences and Series**. Many students find the ‘Quick Reference’ guides useful. Tony Hobson’s **‘Just the Maths’** – section 2.1 is on Series, this includes clear notes and examples and exercises. Younger students will find **Craig Barton’s notes** useful or the **Interactive exercises from the Centre for Innovation in Mathematics Teaching** (see Unit 10).

For more on WolframAlpha see the **WolframAlpha pages.**
