1 is read as "one one" (one number 1) -> 11
11 is read as "two ones" (two number 1) -> 21
21 is read as "one two, one one" (one number 2 then one number 1) -> 1211
1211 is read as "one one, one two, two ones" (one number 1, then one number 2, then two number 1 -> 111221.
SO THE NEXT NUMBER IS: "three one, two two, one one" -> 312211
