Merle was checking out at the grocery store. Ethel, a friendly cashier, said the total was $63.59. He gave her a $100 bill and she began laughing as she counted out his change. Then she gave him a high five and Merle left the store chuckling.
I hesitated to add this because it’s poorly worded, ambiguous and the answer could be almost anything. I prefer teasers with a single answer, but there you go.
If you came up with a different answer and can explain how you did it, don’t think you’re wrong. It’s probably just as valid. Feel free to share yours in the comments.
My answer for the first number is 2.
Here’s how I got it.
The generic rule for a number in the sequence is: 2^(n – 1) + 1, where n is the position in the sequence.
Note: The teaser doesn’t specify the position of 17. In this case, it’s fifth.
Position 1: (so n = 1) is 2^(1 – 1) + 1 = 2
Position 2: 2^(2 – 1) + 1 = 3
Position 3: 2^(3 – 1) + 1 = 5
Position 4: 2^(4 – 1) + 1 = 9
Position 5: 2^(5 – 1) + 1 = 17
For the curious, the next 5 numbers of the sequence would be:
At Coney Island (the amusement park in Ohio) over Memorial Day weekend I saw a changing station in the men’s bathroom. A clever fellow had scraped off some letters to make the changing station read, “Turd Station”. What was the original name of the changing station?
