\r\n" );
document.write( "\r\n" );
document.write( "In the number line, you have this segment  [-10,26]  of the length  10 + 26 = 36.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "They want you insert 8 numbers (8 points in the number line) to divide this segment in 9 (nine) equal parts.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "I am sure that you do understand why I am talking about 9 parts: because 9 = 8 + 1.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Next, it is clear for you, that each part must be  36/9 = 4 units long.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "It means that your points (numbers) are the terms of an arithmetic progression\r\n" );
document.write( "with the first term of -10 and the common difference of 4\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "    -10, -6, -2, 2, . . . \r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "and you can continue it further till 26.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Then the term of this progression, excluding its endpoints, give you the answer to the problem's question.\r\n" );
