Question

Three arithmetic means between 3 and negative 13

Answer 1

Answer:

- 9, - 5, - 1

Step-by-step explanation:

Calculate the mean of 3 and - 13, that is

$\frac{3-13}{2}$ = $\frac{-10}{2}$ = - 5

That is

- 13, - 5, 3

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

$\frac{-13-5}{2}$ = $\frac{-18}{2}$ = - 9

$\frac{-5+3}{2}$ = $\frac{-2}{2}$ = - 1

Thus

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