    -10 - -31 = 21

    To have 2 means there has to be 3 sections so 21/3 = 7

    -31+7=-24

    -24+7=-17

    The two arithmetic means are -24 and -17

    Difference between the extreme values = 21

    To get 2 arithmetic means 21/3 = 7

    Answer -24 and -17

    -31 = (-31*3 + -10*0)/3 and -10 = (-31*0 + -10*3)/3

    The two arithmetic means are:

    (-31*2 + -10*1)/3 = -72/3 = -24 (and if you knew the multiple choice answers then that will be enough), and

    (-31*1 + -10*2)/3 = -51/3 = -17

    Between -31 and -10 is a difference of +21

    In order to have *two* means, we want to divide that into *three* sections:

    21/3 = 7

    So add 7 to get to the first mean:

    -31 + 7 = -24

    And 7 again to get to the second mean:

    -24 + 7 = -17

    As a double-check, notice that adding 7 again gets you to the upper number.

    -17 + 7 = -10

    Answer:

    -24 and -17

    4 and -8 .

  • -31 , -31 + d , -31 + 2d , -10

    -10 = -31 + 3d

    -10 + 31 = 3d

    21 = 3d

    7 = d

    -31 , -31 + 7 , -31 + 2 * 7 , -10

    -31 , -24 , -17 , -10

    -24 and -17

    Arithmetic means are always between. You can find the arithmetic mean OF -31 and -10. and it is -20.5
