1. $\"N=99-9%2B1=91\"$
\n" ); document.write( "2. $\"x=2n\"$ , when $\"n=1\"$ , $\"x=2\"$ , when $\"n=1001\"$ , $\"x=2002\"$
\n" ); document.write( " $\"N=1001\"$
\n" ); document.write( "3.
\n" ); document.write( " $\"x%5B1%5D=0\"$
\n" ); document.write( " $\"x%5B2%5D=x1%2B2%5E%282-2%29=0%2B1=1\"$
\n" ); document.write( " $\"x%5B3%5D=x%5B2%5D%2B2%5E%283-2%29=1%2B2=3\"$
\n" ); document.write( " $\"x%5B4%5D=x%5B3%5D%2B2%5E%284-2%29=3%2B4=7\"$

\n" ); document.write( " $\"N=11\"$
\n" ); document.write( "4. I don't understand the problem. Is it $\"x%5E2\"$ ?? What does 1,3,5,7, or 99 mean?
