write the first five terms of the sequence\r
\n" ); document.write( "\n" ); document.write( "T1 = 1, Tn = 2Tn-1 + 2\r
\n" ); document.write( "\n" ); document.write( "
\r\n" );
document.write( "\r\n" );
document.write( "You already have T1, so you replace n by 2, \r\n" );
document.write( "then by 3, then by 4, then by 5.\r\n" );
document.write( "\r\n" );
document.write( "Tn = 2Tn-1 + 2\r\n" );
document.write( "\r\n" );
document.write( "Replacing n by 2:\r\n" );
