The first four terms of a pattern are shown below: \r
\n" ); document.write( "\n" ); document.write( "ABBA
\n" ); document.write( "AABBBAA
\n" ); document.write( "AAABBBBAAA
\n" ); document.write( "AAAABBBBBAAAA \r
\n" ); document.write( "\n" ); document.write( "Suppose that this pattern continues, with the As and Bs increasing as shown
\n" ); document.write( "Find an expression for the ratio of Bs to total letters in the nth term.
\n" ); document.write( "------------------
\n" ); document.write( "The nth term:
\n" ); document.write( "starts with \"n\" A's
\n" ); document.write( "has \"n+1\" B's
\n" ); document.write( "ends with \"n\" A's
\n" ); document.write( "----------------------
\n" ); document.write( "ratio of B's to A's: (n+1)/(2n)
\n" ); document.write( "=====================================
\n" ); document.write( "Cheers,
