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.
121 to the second power means 121 times 121. 1212 = 121 * 121 = 14,641

These are squares12^211^210^29^28^27^2=496^2=36
Notice the pattern: 12^2 11^2 10^2 9^2 .. So the next term is 6^2=36
