Makes Sense What rule defines the following sequence of numbers? 5, 2, 2.5, 2, 2

Answer: There is a small hint in the problem title; if you consider that there might be a 'pun' in the title, it is:

1 nickel = 5 cents
1 dime = 2 nickels
1 quarter = 2.5 dimes
1 half-dollar = 2 quarters
1 dollar = 2 half-dollars
