That is often called the coefficient.
factor
The coefficient would be the number multiplied by the variable, in this case: 7
(x - 25)*4
8x
Variable is any letter used in an algebraic expression, and can vary (change form) to be any number, and one variable means the same number in any single algebraic expression. Usually algebra is simplifying the expression or equation until you know what the variable is equal to.
It is the coefficient of the variable
