Riddle:
1, 11, 21, 1211, 111221, 312211, 13112221, what comes next?
Answer:
1113213211
Explanation:
This riddle is called “Look and Say Sequence”
Get ready to dive into the intriguing world of number sequences with this captivating riddle! Let’s unravel the pattern hidden within the given sequence: 1, 11, 21, 1211, 111221, 312211, 13112221.
To crack this sequence, we need to carefully observe the numbers and decipher the pattern that governs their progression. Each term in the sequence describes the count or arrangement of digits in the previous term.
Let’s break it down step by step:
- The first term is simply “1.”
- The second term is derived by counting the number of “1”s in the previous term, which gives us “11.”
- The third term is derived by counting the number of “1”s in the second term, resulting in “21.”
- The fourth term follows a unique pattern: it describes the count of consecutive digits in the third term. So, in the third term, we have two consecutive “2”s, which translates to “12” and one “1,” giving us “1211.”
- The fifth term continues the pattern by describing the count of consecutive digits in the fourth term. In “1211,” we have one “1,” one “2,” and two consecutive “1”s, resulting in “111221.”
- The sixth term follows the same logic, yielding “312211” by counting the digits in the fifth term.
- The seventh term continues this pattern, resulting in “13112221.”
Now, what comes next in this intriguing sequence? Applying the pattern, we continue by counting the digits in the previous term. Therefore, the next term would be: 1113213211
And there you have it! Remember, number sequences can be both challenging and fascinating, but with a keen eye for patterns, we can uncover their hidden secrets.
