Given:
The sequence is:
-15,-10,-4, 3, 11, ______
To find:
The next number.
Solution:
We have,
-15,-10,-4, 3, 11, ______
Here, the difference between two consecutive terms are:
![-10-(-15)=-10+15](https://tex.z-dn.net/?f=-10-%28-15%29%3D-10%2B15)
![-10-(-15)=5](https://tex.z-dn.net/?f=-10-%28-15%29%3D5)
Similarly,
![-4-(-10)=6](https://tex.z-dn.net/?f=-4-%28-10%29%3D6)
![3-(-4)=7](https://tex.z-dn.net/?f=3-%28-4%29%3D7)
![11-3=8](https://tex.z-dn.net/?f=11-3%3D8)
It is clear that the difference difference between two consecutive terms is increasing by 1. So, the next difference must be (8+1)=9.
Let the next number be x. Then,
![x-11=9](https://tex.z-dn.net/?f=x-11%3D9)
![x=9+11](https://tex.z-dn.net/?f=x%3D9%2B11)
![x=20](https://tex.z-dn.net/?f=x%3D20)
Therefore, the next number of the sequence is 20.

Answer:
There are 160 cats at the store.
Step-by-step explanation:
There are 40 black cats, which is 25% of all the cats. You are trying to find all the cats at the store, or 100% of the cats at the store. So:
40 = 25%
40(4) = 25% (4)
160 = 100%
There are 160 cats at the store.
Answer:
I prefer the Euclidian approach. Euclidian geometry is easier to relate to more common experiences or things that happen in real life. On the other hand analytical geometry is more complex and is used in more mathematical problems.
