Answer:

5 Arithmetic mean  between -9 and 9

Let's get the mean first (which is also the third mean)

Mean = a₁ + an

           -------------

                 2

Mean = -9 + 9

            -------

               2

Mean = 0

The third mean is 0.

The second and third mean are between -9 and 0 are: -6 and ,3

The fourth and fifth mean between 0 and 9 are:  3 and 6.

Therefore, the means are (in bold fonts):

-9,  -6,  -3,  0,  3,  6,  9
