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?
Answered by The informer
She will have 16 plants. Hope this helped.
Answered by The informer
No wait that's wrong, the actual answer is 27.
Answered by Ms. Sue
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

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