The Number of the Day: $5.5 Million

Original image


In the early 1980s, the Children’s Television Workshop was sued for $5.5 million by the owners of the Beatles catalogue, who said the song “Letter B” (performed by the Sesame Street Beetles) was too similar to “Let It Be.”

Related Fact: The suit was dropped when Michael Jackson bought the Beatles library, and songwriter Christopher Cerf only had to pay $50 in court fees

Fans of number-based brainteasers might find themselves pleasantly stumped by the following question, posed by TED-Ed’s Alex Gendler: Which sequence of integers comes next?

1, 11, 21, 1211, 111221, ?

Mathematicians may recognize this pattern as a specific type of number sequence—called a “look-and-say sequence"—that yields a distinct pattern. As for those who aren't number enthusiasts, they should try reading the numbers they see aloud (so that 1 becomes "one one," 11 is "two ones," 21 is "one two, one one,” and so on) to figure the answer.

Still can’t crack the code? Learn the surprisingly simple secret to solving the sequence by watching the video below.
