Correct answer is Naomi calculation is incorrect and correct monthly interest rate is 2%.
Solution:
We are given that quarterly interest rate =6%
That means interest rate per quarter is 6%.
Since quarter means 3 months, interest rate per 3 months =6%
Hence interest rate per one month=6/3=2%
That means monthly interest rate is 2% which means Naomi calculation is incorrect.
We are given this explicit formula :
![c(n) = -6 + 5(n - 1)](https://tex.z-dn.net/?f=%20c%28n%29%20%3D%20-6%20%2B%205%28n%20-%201%29%20)
In order to find eighth term let us plug n as 8 in this formula:
![c(8) = -6 + 5(8 - 1)](https://tex.z-dn.net/?f=%20c%288%29%20%3D%20-6%20%2B%205%288%20-%201%29%20)
subtracting 8-1 first using pemdas rule
![c(8) = -6 + 5(7)](https://tex.z-dn.net/?f=%20c%288%29%20%3D%20-6%20%2B%205%287%29%20)
multiplying 5 and 7
![c(8) = -6 + 35](https://tex.z-dn.net/?f=%20c%288%29%20%3D%20-6%20%2B%2035%20)
subtracting 35-6
c(8) = 29
So eighth term is 29.
I think it’s c but don’t go with me see if others answer with a different answer :)
