Explanation:
This riddle is a classic example of the “Look and Say” sequence! It’s a fantastic brain teaser that tests your ability to describe what you see, rather than perform a mathematical operation.
To crack this sequence, we need to carefully observe the pattern that governs its progression. Each term is generated by describing the digits of the previous term.
Let’s break it down step by step:
- Term 1: 1 (This is our starting point.)
- Term 2: 11 (We “look at” ‘1’ and “say” “one 1”, so it becomes 11.)
- Term 3: 21 (We “look at” ’11’ and “say” “two 1s”, so it becomes 21.)
- Term 4: 1211 (We “look at” ’21’ and “say” “one 2, one 1”, so it becomes 1211.)
- Term 5: 111221 (We “look at” ‘1211’ and “say” “one 1, one 2, two 1s”, so it becomes 111221.)
- Term 6: 312211 (We “look at” ‘111221’ and “say” “three 1s, two 2s, one 1”, so it becomes 312211.)
Now, what comes next in this intriguing sequence? Applying the pattern to ‘312211’, we “look at” it and “say” “one 3, one 1, two 2s, two 1s”. This generates: 13112221
