<u>Geometric Sequences</u>
The geometric sequence is given as:

Where n is the number of the term, n≥1, and r is the common ratio.
The sum of n terms of the geometric sequence is given by:

We are given: S3=252, a1=192, thus substuting:

Answer:
The discriminant of f is 92, and it has no real zeros
Step-by-step explanation:
The discriminant of a quadratic is
, where the quadratic is in the form
. The discriminant of this one is therefore:

Since the square root of a negative number is imaginary, this quadratic has no real number zeros. Hope this helps!
