4 Απρ 2024 · Find the n’th term in Look-and-say (Or Count and Say) Sequence. The look-and-say sequence is the sequence of the below integers: 1, 11, 21, 1211, 111221, 312211, 13112221, 1113213211, … How is the above sequence generated? n’th term is generated by reading (n-1)’th term. The first term is "1"
In mathematics, the look-and-say sequence is the sequence of integers beginning as follows: 1, 11, 21, 1211, 111221, 312211, 13112221, 1113213211, 31131211131221, ... (sequence A005150 in the OEIS ).
The Conway sequence, also known as the look-and-say sequence, is a sequence of integers that is constructed by describing the digits or groups of digits present in the previous sequence. It was discovered by British mathematician John Horton Conway.
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. For example: 1 is read off as "one 1" or 11. 11 is read off as "two 1s" or 21. 21 is read off as "one 2, then one 1" or 1211. 1211 is read off as "one 1, one 2, then two 1s" or 111221.
The sequence \[1, 11, 21, 1211, 111221, \ldots\] is known as the look-and-say sequence. Why this type of name for the sequence? It is the key point about this sequence. Just try to think of the sequence from a different view of your mind. You may get the answer.

18 Μαρ 2022 · The look-and-say sequence is a numerical sequence that typically starts with 1 and then has the following terms: 1; 11; 21; 1211; 111221; 312211... (Can you guess the next one?) The way the sequence works is that you read the digits aloud to build the next term. For example, how would you read the term 312211?
