Question

Find the four arithmetic means between 3 and 28.
A. 7, 12, 17, 22
B. 8, 14, 18, 24
C. 9, 14, 19, 24
D. 8, 13, 18, 23

Answer 1

divide the range between them into 5 equal parts ....

Answer 2

that pretty much summed it up right there

Answer 3

To find arithmetic mean between any 2 numbers , p and q
Use the formula
\[\huge \frac{ p-q }{ n+1 }\]
to find the common difference between the means.

The common difference here is
\[\huge \frac{ 28-3 }{ 4+1 }=5 \]

Adding 5 to the first term gives you the first arithmetic mean, adding 5 to that gives you the second mean, etc. Therefore, the arithmetic means are 8, 13, 18, and 23.

Answer 4

3+5 =8
8+5=13
13+5=18
18+5=23

Answer 5

8,13,18,23 are the arithmatic means means

Answer 6

okay so if i had to find the four arithmetic means between 12 and -13. now would i do that? @No.name

Answer 7

Yes use the method i gave you , it works everytime

Answer 8

okay so i just do \[\frac{ -13-12 }{ 4+1 }\]

Answer 9

Wait OS is lagging a bit i will response wait

Answer 10

Yes you can do that, Ask your teacher or professor for confirmation

Answer 11

okay when i did that i got \[\frac{ -25 }{ 5 }\] @No.name
