Insert two arithmetic means between 21 and 33

25 and 29

Step-by-step explanation:

let the two arithmetic mean be b and c respectively.

U(1)=21 and since it is the first term then, a=21

2nd term that is U(2)=b

3rd term that is U(3)=c

4th term that is U(4)=33

Now U(2)=(a+d) that is b

U(3)=(a+2d) that is c

U(4)=(a+3d) that is the 4th term

find d using the 4th term

a+3d=33

21+3d=33

3d=33-21

3d=12

d=12÷33

d=4

therefore

b= a+d ( second term)

b=21+4

b=25

then

c=a+2d ( 3rd term )

c=21+2×4

c=21+8

c=29

describing distributions is one of the key skills you’ll need to earn a high score on the ap statistics exam. if you need proof of this, just flip through some past exam questions, which can be found at the collegeboard website. you’ll notice that the first free response question is almost always a question requiring you to look at a graph and describe it.
