A possibility for the first sequence, maybe; but I will just ignore the second sequence.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "75, 15, 25, 5, 15, NEXT\r
\n" ); document.write( "\n" ); document.write( "3*5*5, 3*5, 5*5, 5 , 3*5\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Starting from first term:
\n" ); document.write( "down, up, down, up, down.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Notice that the factors for each term made of combinations of 3 and 5, and none others. After the \"15\", the next term should go DOWN. The only way is for NEXT term to be 3.
\n" ); document.write( " \n" ); document.write( "
\n" );
