Lighter Than What I’m Made Of

Lighter than what
I am made of,
More of me is hidden
Than is seen.

An Iceberg.

One Two Six Sequence

What is the next number in this series?

1, 2, 6, 42, 1806, ___

To get the next number, multiply the previous number in the series by itself plus one:

n × (n + 1).

For example, to get 6, multiply 2 × (2 + 1)
To get 42 multiply 6 × (6 + 1)

Thus, 1806 × 1807 = 3263442

Alone I’m Unknown

Alone I’m unknown,
With my twin I’m twenty,
And triplets make me a warning.

What am I?

The letter ‘X’. A single x is often used in math as an unknown, along with Mr. X. Two together (XX) make the Roman numeral 20, and three signifies a warning for adult only content, or a warning to other programmers of a problem in source code.

Earthen Home Not a Den

This earthen home is not a den.
I’ve seen impressive rows of them.
As lost as any man becomes,
he always finds his way back home.

A grave.

Related Strangers

A man gets off the bus looking for an address and approaches a couple walking in the same direction for directions. The woman says they’re going that way and take him. Along the way the man asks if they’re related. The woman grins and says, “We’re not strangers. This man’s mother is my mother’s mother-in-law.” The man is confused but doesn’t say anything. When he gets back home he tells his wife about the conversation and she can’t figure it out either. They decide to ask their lawyer and he eventually works it out with pen and paper. How are the couple related?

The couple is either a man and his daughter or an uncle and his niece.

An Oddly Priced Fish Shop

A fish shop with odd pricing sells fish for the following prices: A trout costs $20, a salmon is $19, and a plaice comes in at $16. Using their pricing logic, how much would they charge for a mackerel?

$13. The price is calculated by using the position in the alphabet of the first letter of the name of the fish. An Albacore would be $1, a Bandfish would be $2. Note, I do not recommend using this pricing strategy unless you find yourself with an assortment of cheap Zebrafish.
