\n" ); document.write( "In the sequence \"3\", \"9\", \"27\", \"81\" ...\r
\n" ); document.write( "\n" ); document.write( "first term is \"3\"
\n" ); document.write( "second term is \"9\"=>\"3%5E2\"
\n" ); document.write( "third term is \"27\"=>\"3%5E3\"
\n" ); document.write( "fourth term is \"81\"=>\"3%5E4\"\r
\n" ); document.write( "\n" ); document.write( "more terms
\n" ); document.write( "\"3\", \"9\", \"27\", \"81\", \"243\", \"729\", \"2187\", \"6561\", \"19683\", \"59049\", \"177147\", \"531441\", ...\r
\n" ); document.write( "\n" ); document.write( "so, general formula is:\r
\n" ); document.write( "\n" ); document.write( "\"a%5Bn%5D+=+3%5En\" (for all terms given)\r
\n" ); document.write( "\n" ); document.write( "then \"a%5B100%5D+=+3%5E100\"\r
\n" ); document.write( "\n" ); document.write( "\"a%5B100%5D+=515377520732011331036461129765621272702107522001\"-515 quattuordecillion (a cardinal number represented in the U.S. by 1 followed by \"45\" zeros)\r
