5. The nth term of a Sequence is given by an = = n2 - 2n - 6 If the Domain of the Sequence is {1,2,3,4,5} choose the value that is in the Range of the Sequence from the choices below:
3
18
-4
9

The coefficients are the numbers that multiply the variables or letters. Thus in 5x + y - 7, 5 is a coefficient. It is the coefficient in the term 5x. Also the term y can be thought of as 1y so 1 is also a coefficient.A number used to multiply a variable. Example: 6z means 6 times z, and "z" is a variable, so 6 is a coefficient. Variables with no number have a coefficient of 1. ... Example: In ax2 + bx + c, "x" is a variable, and "a" and "b" are coefficients.First of all, coefficent means the number standing in front of a variable.

So, according to the expression, 2 - 5x - 4 + 8, the coefficient is -5.

Why? because it stands in front of the variable.
