\n" ); document.write( "4 10 18 28 40
\n" ); document.write( " 6 8 10 12
\n" ); document.write( " 2 2 2
\n" ); document.write( "for nth term we know we have a n^2 term
\n" ); document.write( " 4 10 18 28 40
\n" ); document.write( "nth 1 2 3 4 5
\n" ); document.write( "n^2 1 4 9 16 25
\n" ); document.write( " 3 6 9 12 15
\n" ); document.write( "therefore the nth term is
