Ms. Black has one begonia plant. If she buys two begonia plants each year for every one she has, how many will she have in four years?

Answer 1

She will have 16 plants. Hope this helped.

Answer 2

No wait that's wrong, the actual answer is 27.

Answer 3

The informer -- your answers are not correct.

Now - 1 begonia
after 1 year = 1 + 2 = 3
2 years = 3 + 6 = 9
3 years = 9 + 18 = 27
4 years = 27 + 54 = 81
5 years = 81 + 162 = 216 plants

Answer 4

Problem is 81+162 is not 216 it's 243
