Conventionally, a lowercase n in italic type refers to a generic use of a number. You can use n when the value of a number is arbitrary or immaterial. For example, you can say “move the insertion point n spaces to the right.” Reserve a lowercase x in italic type for representing an unknown in mathematical equations (a variable) and other such placeholders. See also x.
