You can put this solution on YOUR website! Let the arithmetic means be a1,a2,a3,a4.
Then we have 68,a1,a2,a3,a4,3 are in A.P.
6th term is 3 and first term a=68
6th term is a+5d where a is the first term and d is the common difference.
68+5d=3
5d=-65
d=-13
a1=68-13=55
a2=55-13=42
a3=42-13=29
a4=29-13=16
The four means are 55,42,29 and 16.
