The population of rats is increasing year after year in a village. Find out the missing population from the following information:
Years : 1990 1991 1992 1993 1994 1995
Population : 4 8 16 ? 44 64
Solution
Given statistics follow a pattern like below:
First = 4
Second = 4 * 2
Third = 4 * (2+2)
Fourth = 4 * (2+2+3)
Fifth = 4 * (2+2+3+4)
Sixth = 4 * (2+2+3+4+5)
hence fourth digit will be 28
