document.write( "The first term 11 gives the remainder of 2 when divided by 3, and the common difference of the AP is 3.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "It means that every member of the progression gives a remainder of 2 when divided by 3 - but the number -150 \r\n" );
document.write( "\r\n" );
document.write( "is a multiple of 3, i.e. gives the remainder 0 when divided by 3.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Therefore, the number  -150  is not the term of the progression.\r\n" );
