1. What is the difference between each adjacent pairs of numbers?
2. The bulbs double in number each year.
1. What are the next three terms in the sequence? -1, 9, 19, 29...
2. Geoff planted dahlias in his garden. Dahlias have bulbs that divide and reproduce underground. In the first year, Geoff's garden produced 8 bulbs. In the second year, it produced 16 bulbs, and in the third year it produced 32 bulbs. If this pattern continues, how many bulbs should Geoff expect in the sixth year?
2. The bulbs double in number each year.
9 and 19 are adjacent pairs
A. 38, 37, 32
B. 40, 51, 62
C. 39, 49, 59***
D. 38, 47, 56
I think its C.
The answer choices for #2 are
A. 64 bulbs
B. 512 bulbs
C. 128 bulbs
D. 256 bulbs ***
Is it D?

Using this pattern, we can find the next three terms:
The fourth term = the third term + 10 = 29 + 10 = 39
The fifth term = the fourth term + 10 = 39 + 10 = 49
The sixth term = the fifth term + 10 = 49 + 10 = 59
So, the next three terms in the sequence are 39, 49, and 59.
2. To determine the number of bulbs Geoff should expect in the sixth year, we need to identify the pattern or rule governing the bulb production. Looking at the given information, we can observe that the number of bulbs is doubling each year.
Using this pattern, we can calculate the number of bulbs in the sixth year:
In the fourth year, the number of bulbs = 32 * 2 = 64
In the fifth year, the number of bulbs = 64 * 2 = 128
In the sixth year, the number of bulbs = 128 * 2 = 256
Therefore, Geoff should expect 256 bulbs in the sixth year.
