You can put this solution on YOUR website!
\"a%5Bn%5D+=+3a%5Bn-1%5D\" for n ≥ 2 (a1 = 1)
\n" ); document.write( "what this says is \"a%5Bn%5D\" describes ALL the other terms (except a1)
\n" ); document.write( "a2 = 3
\n" ); document.write( "a3 = 6
\n" ); document.write( "a4 = 9
\n" ); document.write( "a5 = 12
\n" ); document.write( "etc...
\n" ); document.write( "
\n" );
