First, we are going to rewrite it as a parabola equation.
Rewrite.

Divide by 8.

Factor out coefficient.

Then, we are going to convert x into square form.

Convert the whole expression into square form.

Simplify.

Subtract 6 from both sides.

Divide by coefficient.

Rewrite in standard form.
The radius of the circle will be -2. Also, no matter what the sign says, the radius has to always be positive.
Have a nice day! :)
The explicit formula for calculating the sum is

The sum of the nth term of a sequence is expressed as;

a is the first term
d is the common difference
n is the number of terms
For the sequence 0 + 1 + 2 + 3 +...

Similarly for the sequence:
1 + 2+ 3 + 4+...

Taking the product of the sum to get the explicit formula for calculating the sum
