Answer:
or
Step-by-step explanation:
Hello!
Use the quadratic formula:
First, let's convert our equation to standard form of a Quadratic: ax² + bx + c = 0
3x² = 80
3x² - 80 = 0
Note, thats the value of b will be 0, as there is no "bx"
Now, solve:
The solutions are
Hence, the sum of the given GP is 16347
<h2>What is a series?</h2>a series is the cumulative sum of a given sequence of terms. Typically, these terms are real or complex numbers, but much more generality is possible.
<h3>How to solve?</h3>we can identify from the given geomertric series.
first term = a(say) = 3
geometric factor of progression = r(say) = 4
Sum of the first 7 terms = a() ,where n is 7
Sum = 3() = 16348-1
= 16347
Hence, the sum of the given GP is 16347.
