Final answer:
The sum of a finite geometric series can be calculated using the formula for Arithmetic Sequences.
Step-by-step explanation:
The sum of a finite geometric series can be calculated using formula A) Arithmetic Sequences. The formula for the sum of a geometric series is given by:
Sn = (a(1 - r^n))/(1 - r)
Where Sn is the sum of the series, a is the first term, r is the common ratio, and n is the number of terms.
For example, if the first term (a) is 2, the common ratio (r) is 3, and the number of terms (n) is 4, you can plug these values into the formula to calculate the sum of the series: Sn = (2(1 - 3^4))/(1 - 3) = (2(-80))/(-2) = 40.
