Understand Positions in a Sequence

In this activity, we will be writing the positions of numbers in a list.

Look at this sequence of numbers.

   2    4    6    8    10    12    14

We can number them using 1, 2, 3, 4 etc.

But it is better to use the words:

First, second, third, fourth, fifth, sixth, seventh

or the symbols

1st, 2nd, 3rd, 4th, 5th, 6th, 7th

2 is the 1st number in the sequence.

6 is the 3rd number in the sequence.

14 is the 7th number in the sequence.

Does that make sense?

Let's have a go at some questions now.
