Atrout popolation grew from 4 in 1992 to 16 in 1993 and then 64 in 1994 if it continued to grow exponentially approximately how many trout were three in 1995

If the population of trout is growing exponentially then in 1995 the population of trout will be 256.The exponential growth refers to the growth of population exponentially or in a geometric fashion.In this type of growth the number of individual increase by a constant multiple.Here the multiple is four. The multiple of 4 are 4, 16, 64, 256, 1024 in 1992, 1993, 1994, 1995, 1996 respectively.
