The first has neither a common ratio nor a common difference. It isn't clear what the next term will be. It could be two from then on, or it could change to 1 or 3.\r
\n" ); document.write( "\n" ); document.write( "The second is geometric with a common ratio of (-2). The next term will be +48.\r
\n" ); document.write( "\n" ); document.write( "The third is arithmetic with a common difference of 4.
\n" ); document.write( "
\n" );
