Find the 16th term for the sequence a (n)=3-2n.

In the expression given, the "n" is referring to a certain term, in this case, it would be the 16th term. So in order to find the 16th term, all you have to do is substitute n as 16 in the expression, so the answer is . So the 16th term of the sequence is -29.

Explanation given below.

Step-by-step explanation:

The first step is to put the parabola in the form   , which is the standard form of a parabola

Note: a is the coefficient before x^2 term, b is the coefficient before x term, and c is the independent constant term

The axis of symmetry divides the parabola symmetrically. The axis of symmetry has the equation  

Where a and b are the respective values shown above

So, that is how you get the axis of symmetry of any parabola.
