What is the First Number of the Sequence?

If a number in a numeric sequence is 17 and the second number is 3, what is the first number?

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:

Position 6: 2^(6 – 1) + 1 = 33

Position 7: 2^(7 – 1) + 1 = 65

Position 8: 2^(8 – 1) + 1 = 129

Position 9: 2^(9 – 1) + 1 = 257

Position 10: 2^(10 – 1) + 1 = 513

What are the Things?

In one day, 6 things.
In one week, 4 things.
In one month, 2 things.
In one year, 1 thing.

What are the things?

Odd numbers.

In a day, there are 6 odd hours: 1, 3, 5, 7, 9, 11 (ignoring 24-hour time).

In a week, there are 4 odd-numbered days: 1, 3, 5, 7

In a month, there are 2 odd weeks: 1, 3 (no month has 5 full weeks)

And in a year’s 12 months, there is 1 odd number: 1 (the 1 of 12).

I readily agree the year one is a stretch, but I didn’t write it :)

Swallowed the Dead

I’ve swallowed the dead,
Of a torn land’s end.
And I hold the remains,
Of an unknown friend

A mansion once stood,
Where I now lay,
We honor all those
Who gave us today.

What am I?

Arlington National Cemetery, the burial place of soldiers from the United States Civil War. It also houses the tomb of unknown soldiers. General Robert E. Lee’s mansion once stood on the land that is now occupied by the cemetery. And on Memorial Day in the US, we honor all those who died while serving their country’s armed forces.

Turd Station

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?

sTURDy Station2, by Rubbermaid.

Here’s a picture of one without the letters scratched out.

Easy To Touch

You have one of me and I’m easy to touch,
I’m hard to look at, but you can in a clutch.

Yet you’re told to watch me, or get your friends’.
I’m often referred to when you make amends.

You can throw me out but not away,
I cause many pain, every day.

What am I?

Your back. You have one and it’s easy to touch but hard to look it. A common phrase is to “watch your back” and it’s common to “have your friend’s back.” When apologizing, you often want to take back what you said. You can throw out your back, but you can’t throw it away. And back pain causes people pain every day.
