Answer:

the marked choice is correct

Step-by-step explanation:

The initial term is a1 = 100. The common ratio is r = 110/100 = 1.1. The generic term is ...

an = a1·r^(n-1)

Filling in the known parameters, we find the sequence terms sn to be ...

$\boxed{s_n=100(1.1)^{n-1}}$

Step-by-step explanation:

The average of paid time off is the sum of the paid time off (T) of each employee divided by the number of employees(n):
