In mathematical terms, a coefficient is a numerical or constant factor in a term of an algebraic expression. In the sequence of numbers you’ve provided—6, 65, 10, 4—it’s important to specify what you mean by ‘coefficient’ as these numbers do not form a traditional algebraic expression.
If you’re referring to the first number, which is 6, it can be considered as a coefficient if we think of it in the context of a simple equation like 6x + 65 = 0, where 6 is the coefficient of x.
Therefore, in this context, the coefficient is 6, as it is the number that multiplies the variable in the expression.
