<span>9-1 is 8 X 5 is 40, the answer is B.</span>
The sum of the sequence is 750
<h3>How to determine the sum of the series?</h3>
The series is given as:
150, 120, 96, and 76.8,
Start by calculating the common ratio using:
r = T2/T1
This gives
r = 120/150
r = 0.8
The sum of the series is then calculated as:

This gives

Evaluate
S = 750
Hence, the sum of the sequence is 750

Answer:
I think you copied this wrong
Step-by-step explanation:
Most likely g = 2
Therefore (2) + 6(11)
2+66=68
10 divided by 2 is 5, 5 + 8 is 13
thus f(10)= 13
hope this helps
