# Definition:Arbitrarily Large

## Definition

Let $P$ be a property of real numbers.

We say that **$P \left({x}\right)$ holds for arbitrarily large $x$** (or **there exist arbitrarily large $x$ such that $P \left({x}\right)$ holds**) if and only if:

- $\forall a \in \R: \exists x \in \R: x \ge a: P \left({x}\right)$

That is:

*For any real number $a$, there exists a (real) number not less than $a$ such that the property $P$ holds.*

or, more informally and intuitively:

*However large a number you can think of, there will be an even larger one for which $P$ still holds.*
