document.write( "Solution:\r\n" );
document.write( "Start with 7 and subtract 1/2. I will use the decimal form of 1/2 because decimals display \r\n" );
document.write( "between on this website, and they are easier to manipulate. (1/2 = 0.5)\r\n" );
document.write( "7 - 0.5 = 6.5\r\n" );
document.write( "\r\n" );
document.write( "The first number is 6.5. (We don't use 7 because 7 does not precede 7.)\r\n" );
document.write( "\r\n" );
document.write( "Repeat this process until you have 7 numbers. The numbers are\r\n" );
document.write( "6.5, 6.0, 5.5, 5.0, 4.5, 4.0, 3.5\r\n" );
document.write( "\r\n" );
document.write( "We find the average of a set of numbers by finding their sum and dividing it by the number \r\n" );
document.write( "in the set.\r\n" );
document.write( "6.5 + 6.0 + 5.5 + 5.0 + 4.5 + 4.0 + 3.5 = 35\r\n" );
document.write( "\r\n" );
document.write( "35 divided by 7 is 5.\r\n" );
document.write( "\r\n" );
document.write( "What is the average of seven numbers, preceding 7, each decreasing by 1/2 is 5.\r\n" );
