The missing term is $\boxed{10202}$.
The sequence is generated by starting with the number 3, and then multiplying it by 3 and adding 1 to get 10. Then, we multiply 10 by 3 and add 1 to get 101. Continuing this pattern, we multiply 101 by 3 and add 1 to get 10202.
Option A, 10101, is incorrect because it does not follow the pattern of multiplying by 3 and adding 1.
Option B, 10201, is incorrect because it does not follow the pattern of multiplying by 3 and adding 1.
Option C, 10202, is correct because it follows the pattern of multiplying by 3 and adding 1.
Option D, 11012, is incorrect because it does not follow the pattern of multiplying by 3 and adding 1.
