\r\n" );
document.write( "You have two numbers at the ends, 12 and -16.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "When you insert 3 arithmetic means between them, you will have 4 intervals/segments between  -16  and  12.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "The full length of the segment  [-16,12]  is  12 - (-16) = 12 + 16 = 28.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Hence, the length of each smallest interval/segment between the neighbor values will be   = 7.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "So, your sequense is \r\n" );
document.write( "\r\n" );
document.write( "-16, -16+7 = -9,  -9+7 = -2,  -2+7 = 5   and  5 +7 = 12.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Answer.  The three arithmetic means to insert are  -9,  -2,  and 5.\r\n" );
