a. 1,6,11,16,21,...
\n" ); document.write( "linear +5 every time
\n" ); document.write( "b. -1,7,15,23,31,...
\n" ); document.write( "linear +8 every time
\n" ); document.write( "c. 1,21,31,41,...
\n" ); document.write( "I think the first term should be 11 and not 1.
\n" ); document.write( "Now it is linear: +10 every time
\n" ); document.write( "d. 1,3,9,27,81,
\n" ); document.write( "NOT LINEAR: x3 every time
\n" ); document.write( "
\n" );
