Which term refers to a number that never changes?

Explanation:
A constant is a value that stays the same in a given situation. In expressions and equations, the variable can take different values, while constants do not change. For example, in y = 3x + 5, x is the variable, 3 is a fixed multiplier called a coefficient, and 5 is a fixed number—the constant term. The exponent tells you the power of a base, which is a different idea from a quantity that never changes. So the term that refers to a number that never changes is constant.
