The three numbers are 66,264 and 132
Solution:-
let the third number be x.
So,the second number will be 2x
and the first number will be 4x
Average = Sum of all the numbers / total numbers
Therefore, (4x + 2x+ x) / 3 = 154
                   x=66
 4x= 4*66 =264
 2x = 2*66 = 132
x= 66

Let third no =x
then second no=2x
then first no=4x 
the average =x+2x+4x/3=154
                 7x=154*3
                  x=154*3/7
                   x=22*3
                     x=66
third no is 66
