1/k+1=k+1/9=5/8k-1\r
\n" ); document.write( "\n" ); document.write( "K+1×k+1=9\r
\n" ); document.write( "\n" ); document.write( "(K+1)^2=9\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "K+1=√9\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "K+1=+-3\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Take k+1=3\r
\n" ); document.write( "\n" ); document.write( "K=3-1
\n" ); document.write( "K=2\r

\n" ); document.write( "\n" ); document.write( "K=2. Ans\r

\n" ); document.write( "\n" ); document.write( "Take k+1=-3
\n" ); document.write( " K=-3-1
\n" ); document.write( " K=-4 \r
