Best Answer

There is no number right before infinity. One could say that the number before infinity is "infinity minus one", but you cannot use normal subtraction with infinity. Infinity - 1 is still mathematically defined as infinity, as is Infinity + 1.

Perhaps the question is referring to the largest number with its own name (other than infinity, which, as previously stated, is not technically a number). A googol is often cited as this number. A googol is defined to be a 1 with a hundred zeroes after it.

Alternatively, a googolplex might qualify for the title of largest number with its own name, being a 1 with a googol zeroes after it.

A couple of quick side notes are in order here:

There are not a googolplex atoms in the visible universe. It is an extremely big number.

The search engine company Google named their company after a googol, because of vast amount of information that they process and organize.
