Answer:
Explanation given below.
Step-by-step explanation:
The first step is to put the parabola in the form , which is the <em>standard form of a parabola</em>
<em />
<u>Note:</u> 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 <em><u>a and b are the respective values shown above</u></em>
<em><u /></em>
So, that is how you get the axis of symmetry of any parabola.
Since the sequence is arithmetic, we have an expression of the form:
Where,
a1: first term of the sequence
d: common difference
n: number of terms
We look for the common difference:
Then, setting values we have:
Then, the sum of the terms is:
Substituting values:
