Explanation:

The formula for a GS is:

a1, a1r, a1 r^2, a1r^3 .....

Examples are:

1. First term a1 =2 and common ratio r = 3, the first 4 terms are:

2, 2*3, 2*3^2, 2*3^3

= 2, 6, 18, 54

2. a1 = 1 , r = 0.5:

1, 0.5, 0.25, 0.125 .....

3. a1 = -4, r = -2:-

-4, 8, -16, 32 ...

4. a1 = 0.1, r = -3:

0.1, -0.3, 0.9, -2.7 .....

5. a1 = 2, r = 1/3:

2, 2/3, 2/9, 2/27 .....
