12 subtract by 1 is 11
Have a nice day!
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:
The first and fourth are called extremes and the second and third are called means.
Answer:
60 ft
Step-by-step explanation:
We need to figure the Perimeter of a rectangle with 2L + 2W.
