Answer:
The amount in the account in the beginning of the 6th year is $6375 .
Step-by-step explanation:
Formula
As given
You invest $5000 in an account at 5.5% per year simple interest.
Principle = $ 5000
Rate = 5.5 %
Time = 5 years
(As calculate amount in the account for beginning of 6th year.)
Putting all the values in the formula
Simple interest = $ 1375
Amount = Principle + Simple interest
Putting values in the above formula
Amount = $5000 + $1375
Amount = $ 6375
Therefore the amount in the account in the beginning of the 6th year is $ 6375 .
Answer:
The common difference d is d = -3
The recursive formula is:
Step-by-step explanation:
We need to find the common difference and the recursive formula.
a. 22, 19, 16, 13, …
First we will find common difference
The formula of arithmetic sequence is:
where a_n is nth term, a_1 is 1st term and d is the difference
Looking at the sequence we get: a_1=22, a_2=19
Using these values we can find d, the common difference
So, the common difference d is d = -3
Now, we will find the recursive formula:
The recursive formula is of type:
We have found common difference d = -3
So, the recursive formula will be:
The recursive formula is:
