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?

Answer 1

Answer:

2048

Explanation:

The bulbs increase in a multiple of 2

Using the formula a(a^n) where a = 2 and n is the number of year

1 yr = 4

2yr = 8

3 yr = 16

4 yr = 32

5 yr = 64

6 yr = 128

7 yr = 256

8 yr = 512

9 yr = 1024

10 yr = 2048
