What does infinity look like in numbers?

Answer 1

In mathematics, infinity is not a specific number but rather a concept that represents something endless or unbounded. When we talk about infinity in numbers, we are referring to the idea of a quantity that has no limit. In some contexts, infinity can be represented symbolically as ∞, but it is important to note that infinity is not a real number and cannot be used in typical arithmetic operations.

Answer 2

Infinity is technically an innumerable concept. The way most mathematicians describe it is to use an ellipsis ("...") to state that a concrete pattern continues to infinity. For example, the set of integers is usually noted as { ... -3, -2, -1, 0, 1, 2, 3, ... }, implying that every negative whole number comes before it and every positive number comes after it. For, say, a sequence of numbers starting at 1 and multiplying each term by half, you'd see { 1, 1/2, 1/4, 1/8, 1/16, ... }.
