A variable
Letters and symbols are used in equations to represent quantities, sometimes known or unknown. For example the symbol π (pi) represents the constant 3.14… and is unchanging. X or Y in an equation represent unknown terms that may vary depending on the equation, and other variables in the equation. There are numerous examples of both symbols and letters used in mathematical equations, but almost always they are either referring to a known constant term that is more simply expressed as a symbol, or an unknown or general term yet to be concretely determined.
It is a variable and is expressed as a letter as for example it could be x or y
In maths most vairables are represented with letters. EG. A+B=C So for a best guest and in this case i would say X would be the best for an unknown variable that could change, as x is normally associated with many unknowns.
In maths the symbols x and n are usually used to represent an unknown quantity. These may be referred to as a variable.
x
X is the symbol for multiplication, as in 2X2=4 X (or any other letter) is often used to represent an unknown quantity.
