2, 4 , 16,...
The above equation is neither arithmetic nor geometric because it doesnot have a common difference and a common ratio
The difference between 4 and 2 is 2
The difference between 16 and 4 is 12
Thus the difference is not constant
The ratio of 4 to 2 is 2
The ratio of 12 to 4 is 3
Thus the ratio is not constant
