# Formally Ordered Number Sequence

(Redirected from Formal Number Sequence)

A Formally Ordered Number Sequence is an ordered number sequence that is defined with an algebraic system (with arithmetic operations).

**AKA:**Number Field, Explicit Numeric Sequence.**Context:**- It can be a Supersequence to a Number Sequence, such as a Numeric Interval.
- It can range from being a Formally Ordered Continuous Number Sequence to being a Formally Ordered Discontinuous Number Sequence.
