Suppose the number of rabbits doubles every year on Daniel’s farm. If he currently has six rabbits, how many will Daniel have after four years?

So we know that Daniel’s farm began with six rabbits. And after one year, the number of rabbits should double. So we should multiply by two every year. So he now has 12 rabbits. After another year goes by, so the second year, the number of rabbits double. And he has 24 rabbits.

After another year goes by, which will be the third year, the number of rabbits double. So now we have 48, because 24 times two is 48. Moving down here since we ran out of room, we need to pass by one more year. So this will be the fourth year. And we need to double the amount of rabbits. So 48 times two would mean that, after four years, Daniel will have 96 rabbits on his farm.
