Question

Geoff planted dahlias in his garden. Dahlias have bulbs that divide and reproduce underground. In the first year, Geoff’s garden produced 4 bulbs. In the second year, it produced 8 bulbs, and in the third year, it produced 16 bulbs. If this pattern continues, how many bulbs should Geoff expect in the tenth year?

A). 2,048 bulbs

B). 1,024 bulbs

C). 40 bulbs

D). 32 bulbs

Answer 1

The answer b I think or a

Answer 2

I think it's A). 2,048

Explanation:

I did the problem.

4 * 2 = 8 2nd year

8 * 2 = 16 3rd year

16 * 2 = 32 4th year

32 * 2 = 64 5th year

64 * 2 = 128 6th year

128 * 2 = 256 7th year

256 * 2 = 516 8th year

516 * 2 = 1024 9th year

1024 * 2 = 2048 10th year

If 2048 isn't correct, than the answer is B?. 1,024
