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?

She will have 16 plants. Hope this helped.
No wait that's wrong, the actual answer is 27.
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
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
Problem is 81+162 is not 216 it's 243
