\n" ); document.write( "pattern:\r
\n" ); document.write( "\n" ); document.write( "The next number is the sum of the previous $\"3\"$ numbers
\n" ); document.write( "So:
\n" ); document.write( "If we start with $\"1\"$ , $\"1\"$ , $\"1\"$ next one is $\"1%2B1%2B1+=+3\"$
\n" ); document.write( "We have $\"1\"$ , $\"1\"$ , $\"1\"$ , $\"3\"$ next one is $\"1%2B1%2B3+=+5\"$
\n" ); document.write( "We have: $\"1\"$ , $\"1\"$ , $\"1\"$ , $\"3\"$ , $\"5+\"$ next one is $\"1%2B3%2B5+=+9\"$
\n" ); document.write( "We have: $\"1\"$ , $\"1\"$ , $\"1\"$ , $\"3\"$ , $\"5+\"$ , $\"9\"$ next one is $\"3%2B5%2B9+=+17\"$
\n" ); document.write( "We have: $\"1\"$ , $\"1\"$ , $\"1\"$ , $\"3\"$ , $\"5+\"$ , $\"9\"$ , $\"17\"$ next one is $\"5%2B9%2B17+=+31\"$ \r
\n" ); document.write( "\n" ); document.write( "We have: $\"1\"$ , $\"1\"$ , $\"1\"$ , $\"3\"$ , $\"5+\"$ , $\"9\"$ , $\"17\"$ , $\"31\"$ next one is $\"9%2B17%2B31+=+57\"$
\n" ); document.write( "We have: $\"1\"$ , $\"1\"$ , $\"1\"$ , $\"3\"$ , $\"5+\"$ , $\"9\"$ , $\"17\"$ , $\"31\"$ , $\"57\"$ next one is $\"17%2B31%2B57+=+105\"$ \r
\n" ); document.write( "\n" ); document.write( "We have: $\"1\"$ , $\"1\"$ , $\"1\"$ , $\"3\"$ , $\"5+\"$ , $\"9\"$ , $\"17\"$ , $\"31\"$ , $\"57\"$ , $\"105\"$ next one is $\"31%2B57%2B105+=+193\"$ \r
\n" ); document.write( "\n" ); document.write( "and so on...I hope you will be able to do it up to the 2019th member of this sequence\r
