Step-by-step explanation:
<u>Geometric Sequences</u>
The geometric sequence is given as:

Where n is the number of the term, n≥1, and r is the common ratio.
The sum of n terms of the geometric sequence is given by:

We are given: S3=252, a1=192, thus substuting:

Answer:
It will take 146 days to earn an interest of $80.
Step-by-step explanation:
The simple interest formula is:

It is provided that:
I = $80
P = $4,000
r = 5% p.a.
Compute the time required as follows:


   
Thus, it will take 146 days to earn an interest of $80.
