You can use GP in many ways.
- Suppose you invested some money at somewhere.The money increases in a constant ratio.You can use geometric sequence in order to find your money after some years.

The answer is A, 1. In the statement x^2 >x, if we try 4, 5 and 8 for x, we get 16, 25 and 64 for x^2. The statement is true. But if we try x = 1, when we square it we still have 1. Therefore for x=1, x^2>x is false.
