TED-Ed: Can you find the next number in this sequence? - Alex Gendler

The video tutorial explains the look and say sequence, a pattern based on the notation of numbers rather than their mathematical properties. It describes how to read and write the sequence, its unique properties, and its growth pattern, which converges to Conway's Constant. The sequence eventually breaks down into distinct strings of digits, with 92 identified elements. The tutorial also highlights practical applications, such as run-length encoding, demonstrating how numbers and symbols can convey meaning on multiple levels.
