Q. Find the sum of the infinite geometric series.−8−524−2572−125216+Write your answer as an integer or a fraction in simplest form.______
Identify Terms: Identify the first term a and the common ratio r of the geometric series.The first term a is −8.To find the common ratio r, we divide the second term by the first term.r=5−24/(−8)=53
Check Convergence: Check if the absolute value of the common ratio is less than 1 to ensure the series converges.∣53∣=53, which is less than 1, so the series converges.
Use Sum Formula: Use the formula for the sum of an infinite geometric series, which is S=1−ra, where S is the sum, a is the first term, and r is the common ratio.S=1−(53)−8
Calculate Sum: Calculate the sum using the formula.S=1−(53)−8S=52−8S=−8×(25)S=2−40S=−20
