The Rule of 72 is a basic method to decide how stretched an investment will take to double. It is specified with a fixed annual rate of interest. The annual rate of return would be divided by 72, stockholders can now get an approximate guess of how many years it will take for the original investment to duplicate itself.

So basically, the formula is 72/r where r is the annual rate. So the solution for this is to divide 72 by 18, to get the answer. The answer is 4 years.
