Second question:

A) 96

B) 1000000000000000000000000000000000\

0000000000000000000000000000000000\

000000000000000000000000000000000

C) Either of the above

D) None of the above

And here are the answers:

First question answer is:

one

one one (Since the previous line has one time one number)

two ones (Since the previous line has two time one number)

one two one one

one one one two two ones

So the next line answer is 3 1 2 2 1 1

Second question answer is:

ten, nine, sixty, ninety, seventy, sixty-six,

Each number has one letter more than the previous number, ten has 3 letters, nine has 4 letters etc'

Thanks for this little insight. I've got to run and short GOOG stock now.

For the first question, is that the official answer? Or is it your version? Because 1112221111 is just as well an answer (each number is composed by combining the halves of the previous two numbers, and then switched)

The second question is my own version, I'm pretty sure it's the right answer.
