    ★suppose the mean : -

    a1 , a2, a3 , a4.

    ★therefore : -

    ★the sequence will be like this : -

    ap - 68 , a1 , a2 , a3 , a4 , 3

    6th term   = 3

    a1 = 68

    sixth term = a + 5d

    68 + 5d = 3

    5d = -65

    d = -13

    ★now put the value we get : -

    a1 = 68 - 13

    = 55

    a2 = 55 - 13

    = 42

    a3 = 42 - 13

    = 29

    a4 = 29 - 13

    = 16

    ★4 means - 55 , 42 , 29 ,16.
