1) the common difference between any two successive terms is -2\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "the next term is -3-2 or -5\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "the nth term is -2n+5\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "2) there is no common difference or common ratio __ these are characteristics of a series with an exponent other than 1\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "dividing by -3 gives 1, 8, 27, 64, ... __ these are perfect cubes\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "the next term is -375\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "the nth term is -3n^3
\n" ); document.write( "
\n" );
