"20" must be read: "At position 2, there is a 0". And indeed, there is, when considering the sequence as a string of concatenated digits;
"40" reads: "At position 4, there is a 0" - which is true;
"34" reads: "At position 3, there is a 4" - which is also true;
...
"200" reads: "At position 20, there is a 0" - which is true (the central 0 in 300); etc.
