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).
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"
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.
15 Οκτ 2017 · Read the digits out loud to find the pattern. A semi-interesting note about this sequence is that you will never get a number greater than 3 3. It's known as the look-and-say sequence. In the first row, there is one 1 (11). In the second, two 1s (21). In the third, there is one 2 then one 1 (1211).
26 Νοε 2024 · The integer sequence beginning with a single digit in which the next term is obtained by describing the previous term. Starting with 1, the sequence would be defined by "1, one 1, two 1s, one 2 one 1," etc., and the result is 1, 11, 21, 1211, 111221, ....
1, 11, 21, 1211, 111221, \ldots 1,11,21,1211,111221,… 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.
24 Νοε 2024 · Look at the number, visually grouping consecutive runs of the same digit. Say the number, from left to right, group by group; as how many of that digit there are - followed by the digit grouped. This becomes the next number of the sequence. An example: Starting with 11, you have two 1's. I.E.: 21. Starting with 21, you have one 2, then one 1.
