Find the missing number 14 9 12 12 10 15 8 18 6 21 24?
13168? hmm too short to know for sure. But there is a pattern I found.
For the first number the difference from 2 and 0 is 2. So you times the difference by 2 (the number) and then add 1 to get 5.
For the second number the difference from 5 and 2 is 3. So you times 3 (the difference) by 5 the number and then subtract 1 to get 14.
For the third number the difference from 14 and 5 is 9. So 9 times 14 and then you subtract 4 to get 122.
So, for the next number you would take the difference from 122 and 14 which is 108, then times that by 122 and get 13176, then following the pattern of (1, -1, -4) you would subtract 13176 by 8 to get 13168.

E: Flower.
A poem is created.
A novel is created.
A painting is created.
A statue is created.
A flower is.... Grown.
Alternatively:
A poem is a text.
A novel is a text.
A painting is a text.
A statue is a text (yes, it's a text).
A flower is... A flower.
We can also do the same with "is man made" or "is not a natural creation" "is inanimate" and so on.
Flower is unlike the others.
It is an inverse statement, which is not necessarily true. It is one of the laws of logic and logical reasoning.
What makes it illogical is:
- It may be cold but not cold enough.
- It can be too cold to snow.
- The air may be dry; without moisture, it will not snow.
- It may have snowed before and it may snow later, but it is not snowing now.
- It may be cold without snow falling because the temp is warming.
- It may be cold without snow falling because it is raining.
- It may be cold without snow falling because sleet is falling instead.
