Find sn for the given geometric series. round answers to the nearest hundredth, if necessary.
a1= 0.28,a5 = 362.88, r = 6
select one:
a. 435.4
b. 51.4
c. 311.08
d. 874.94

a. 435.4

Step-by-step explanation:

We are given a geometric sequence with first term, firth term and the common ratio. We are asked to find the sum of first 5 terms of the geometric series.

The formula to calculate the sum of finite geometric series is:

Since we need to find the sum of first 5 terms, n will be 5. Using these values in the above formula, we get:

Therefore, the sum of first 5 terms of the given geometric series would be 435.4
