The sequence appears to be generated by describing the previous term. The first term "121" can be described as "one 1, one 2," leading to "212." The second term "212" is described as "two 1s, one 2," resulting in "221112." Then, "221112" is described as "two 2s, one 1, one 2," which gives "1211." Therefore, the next term in the sequence is 1211.
