The series is a geometric series and the sum of the first 8 terms of the series 48, 60, 75 is 952.32
<h3>How to determine the sum of the first 8 terms?</h3>The series is given as:
48, 60, 75
The above series is a geometric series with the following parameters:
First term, a = 48
Common ratio, r = 1.25
The sum of n terms is:
So, we have:
Evaluate
Hence, the sum of the first 8 terms of the series is 952.32

Answer:
The location will be at units.
Step-by-step explanation:
A scuba diver descended at a rate of units per second.
Now, if 0 represents the surface of the water and distances below the surface are negative, then after seconds the location of the diver will be given by the followings :
In one second the diver descends by 2.25 units depth.
So, in 12.5 seconds the diver will descend by units i.e.
units depth.
Therefore, the location will be at units. (Answer)
