Answer:
In the expression n + 23, 23 is a term.
A term is a single number, variable, or a product of numbers and variables that are separated by addition or subtraction operators. In this case, n and 23 are separate terms, with 23 being a constant term since it has no variable attached to it.
A coefficient is the numerical factor of a term, while a factor is a number or variable that is multiplied by another number or variable to obtain a product. However, in the expression n + 23, there is no coefficient or factor associated with 23.
