Explanation

The pattern involves adding an extra '1' to the sequence of ones between the 3 and the 00. The sequence is 20, 300, 3100, 31100, 311100. Following this, the next term should have four ones: 3111100.

AI explanation

The series is generated by alternately multiplying by 10 and adding 100 to the previous term. Multiplying 20 by 10 and adding 100 gives 300, multiplying 300 by 10 and adding 100 gives 3100, and multiplying 3100 by 10 and adding 100 gives 31100. Continuing this pattern for the last term, multiply 311100 by 10 and add 100 to get 3111100.
