Answer:
The distance between points A and B is 3 units
Step-by-step explanation:
We need to find distance between points on the number line.
The points given are:
A = -1 , B = 2
The formula used is: ![Distance = |b-a|](https://tex.z-dn.net/?f=Distance%20%3D%20%7Cb-a%7C)
Putting values of a and b and finding answer:
![Distance = |b-a|\\Distance = |2-(-1)|\\Distance=|2+1|\\Distance=|3|\\Distance = 3](https://tex.z-dn.net/?f=Distance%20%3D%20%7Cb-a%7C%5C%5CDistance%20%3D%20%7C2-%28-1%29%7C%5C%5CDistance%3D%7C2%2B1%7C%5C%5CDistance%3D%7C3%7C%5C%5CDistance%20%3D%203)
So, The distance between points A and B is 3 units

Option → A
Answer:
h(1)=-13
![h(n)=h(n-1)-13, n\geq 2](https://tex.z-dn.net/?f=h%28n%29%3Dh%28n-1%29-13%2C%20n%5Cgeq%202)
Step-by-step explanation:
We are given that
![h(n)=-13n](https://tex.z-dn.net/?f=h%28n%29%3D-13n)
We have to find the recursive formula of h(n).
Substitute n=1
![h(1)=-13](https://tex.z-dn.net/?f=h%281%29%3D-13)
n=2
![h(2)=-13-13=-26=h(1)-13](https://tex.z-dn.net/?f=h%282%29%3D-13-13%3D-26%3Dh%281%29-13)
n=3
![h(3)=-13(3)=-39=-26-13=h(2)-13](https://tex.z-dn.net/?f=h%283%29%3D-13%283%29%3D-39%3D-26-13%3Dh%282%29-13)
![h(4)=-13(4)=-52=-39-13=h(3)-13](https://tex.z-dn.net/?f=h%284%29%3D-13%284%29%3D-52%3D-39-13%3Dh%283%29-13)

:
![h(n)=h(n-1)-13](https://tex.z-dn.net/?f=h%28n%29%3Dh%28n-1%29-13)
Therefore, the recursive formula is given by
h(1)=-13
![h(n)=h(n-1)-13, n\geq 2](https://tex.z-dn.net/?f=h%28n%29%3Dh%28n-1%29-13%2C%20n%5Cgeq%202)
