Video Transcription

David writes, in increasing order, all the integers from 2 to 2022, which use only zeros and twos. What's the number in the middle of his list?  So he writes down 2, 20, 22, 200, 202, 220, 222, 2000, 2002, 2020, and 2022. He wrote down 11 numbers in total, and the middle one is this one right here.  So that means our final answer is B, 220.
