What is 1 11 21 1211?
In mathematics, the look-and-say sequence is the sequence of integers beginning as follows: 1, 11, 21, 1211, 111221, 312211, 13112221, 1113213211. To generate a member of the sequence from the previous member, read off the digits of the previous member, counting the number of digits in groups of the same digit.
What is the 4th sequence of look and say problem?
This sequence is constructed in the following way: The second number is read as “Two 1s”. Hence, the third number will be 21. The third number is read as “One 2, One 1”. Hence, the fourth number will be 1211.
