Average = sum/(# of numbers)


\n" ); document.write( "For the six numbers, the problem gives (8+9+16 + (sum of other three))/6 = 12


\n" ); document.write( "8+9+16= 33 and call the Sum of the other three numbers S.


\n" ); document.write( "33 + S = 72


\n" ); document.write( "S= 72-33=39


\n" ); document.write( "Apply the average formula. S is the sum of the three numbers, and there are 3. S/3 = average. 39/3 = 13 is the average of the other three numbers. \n" ); document.write( "
