You can put this solution on YOUR website!
this is a geometric sequence ___ each term is 5 times the previous term , so the common ratio (r) is 5\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "starting with some term \"a\" ___ a , a(5) , a(5^2) , a(5^3) , etc\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "you can see that the nth term would be ___ a[5^(n-1)] \n" ); document.write( "

\n" );
