which of the following is the sum of the first five terms of the geometric series whose first term is a and that has a common ratio
•? (1 point)
The sum of the first five terms of a geometric series can be calculated using the formula:
S = a(1 - r^n) / (1 - r)
where:
S = sum of the first n terms
a = first term
r = common ratio
n = number of terms
In this case, the sum of the first five terms would be:
S = a(1 - r^5) / (1 - r)
