The following activity is a practice exercise to help you measure your success under timed conditions.

If you are unsure of an answer, move on to the next question.

You should come back to questions you found difficult at the end if you have time.

 

 

Let’s try one together as a reminder:

 

Here is a sequence of numbers called triangle numbers. Can you work out the pattern?

1, 3, 6, 10, 15, 21

 

In this sequence, the amount added each time is going up by one.


The next number in this sequence would be 28 as we need to add 7 next to 21.

 

 

Now it's time to begin this practice exercise.
