Sixteen, Twenty-six, Then What?

Fill in the missing numbers in this number series.

16, 26, ?, 43, 50, ?, 61, 65, ?, 70, 71

The method to create the series is start by adding 10, then decrease the addend by 1 for each new number in the sequence. That gives us:

16 + 10 = 26
26 + 9 = 35
35 + 8 = 43
43 + 7 = 50
50 + 6 = 56
56 + 5 = 61
61 + 4 = 65
65 + 3 = 68
68 + 2 = 70
70 + 1 = 71

What is the Five Digit Number?

What 5-digit number satisfies the following requirements?

1. No zeroes
2. First two digits are the same
3. Fourth digit is twice the first
4. Last digit is twice the third
5. Sum of all digits is 18

33264.

There are several ways of solving this. One way is to represent each spot with a letter, A – E.

Then you have these equations:

A = B
D = 2 * A
E = 2 * C
A + B + C + D + E = 18

By simplifying, you get:

4 * A + 3 * C = 18

Plug in values for A and C to find that A = 3 C = 2.

A Date With No Numbers

How can you write a date in 5 letters without using any numbers?

The most popular answer for this teaser is ‘today’. Of course this only works if you’re reading it on that particular date or if the date is not specified. Another option is to respond literally with ‘a date’. Lastly, certain dates could be squeezed into letters using Roman numerals if you abbreviate the year to 2 numerals. For example, January 20th, 2011 would be I XX XI.

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.

Can’t Be Touched, Can Be Felt

It can’t be touched, but can be felt.
It can’t be opened, but can be gone into.
Those who seek it always find it under something,
yet it moves from place to place.

Shade. You can’t touch shade, but you can feel its coolness. You can’t open shade but you can go into it. If you’re looking for shade it always has to be underneath something to block the light and shade moves as the light does.
