<pre>
          The first term is given, so

1. The first term is 5.

          5 times the common ratio 2 is 10, so 

2. The second term is 10.

         10 times the common ratio 2 is 20, so 

3. The third term is 20.

         20 times the common ratio 2 is 40, so 

4. The fourth term is 40.

So the first four terms are 5, 10, 20, 40.
