It would be called a variable, and can be symbollized by anything, but the letters x and y are common.

Variables (letters like x and y)
A letter or symbol that stands for a number or numbers is called a "variable." In mathematics, variables are used to represent unknown values and can take on different values in equations or expressions. Commonly used variables include letters such as x, y, and z.

variables (like 2*y=14) PS the variable is 7 :]
Zillion is not a proper number: it is used to signify a very large, but unspecified amount.
Usually this symbol: %
There is no specific symbol. The symbol for real numbers is R and that for rational numbers is Q so you could use R \ Q.

A large but unspecified amount of number is called an umpteen. Despite the suffix -teen in the term, it is used to indicate all numbers beyond 19.
