Spell the numbers out:

Ten

Nine

Sixty

Ninety

Seventy

Sixty-six

They are in ascending order, based on the number of letters in the spelled-out numbers. A correct response will have nine letters: 96, for instance. A cleverer answer is "one googol." That’s the huge number that can be written as a "1" with a hundred zeros after it. Google, the company’s name, was originally a misspelling of "googol."
