The total is 7*39=273.
\n" ); document.write( "Two numbers are known, 31 and 53, and they make 84.
\n" ); document.write( "The other 5 must add up to 273-84= 189.
\n" ); document.write( "The smallest is 33, the largest 51.
\n" ); document.write( "The average value is 37.8
\n" ); document.write( "At least 3 numbers have to be below that, and they would be 33,35,37, whose sum is 105.
\n" ); document.write( "That leaves 84 for the other two, and they are 41 and 43.\r
\n" ); document.write( "\n" ); document.write( "The list of numbers is
\n" ); document.write( "31,33,35,37,41,43,53. They average to 39, and the number in the middle is 37.
