Question

Three arithmetic means between 3 and negative 13

Answer 1

- 9, - 5, - 1

Explanation:

Calculate the mean of 3 and - 13, that is

`(3-13)/(2)` =
`(-10)/(2)` = - 5

That is

- 13, - 5, 3

Now find the mean of - 13 and - 5, and - 5 and 3

`(-13-5)/(2)` =
`(-18)/(2)` = - 9

`(-5+3)/(2)` =
`(-2)/(2)` = - 1

Thus

- 13, - 9, - 5, - 1, 3
