Answer:
2027 = $122.25
2016 = $48
Step-by-step explanation:
Find 1% of 75
75 / 100 = 0.75
multiply by 9
0.75 * 9 = 6.75
So that's $6.75 each year
Now, lets find our answers for 7 years.
6.75 * 7 = $47.25
75 + 47.25 = $122.25
<u>The stock will be $122.25 in 2027</u>
Now for 2016.
$6.75 * 4 = $27
$75 - $27 = $48
<u>The stock was $48 in 2016</u>

<h3><u>
Answer:</u></h3>
Hence, the sum of a 7-term geometric series is:
-32766.
<h3><u>
Step-by-step explanation:</u></h3>
We have to find the sum of a 7-term geometric series (i.e. n=7) if the first term(a) is -6, the last term is -24,576, and the common ratio(r) is 4.
We know that the sum of the 7-term geometric series is given as:

On putting the value of a,n and r in the given formula we have:

Hence, the sum of a 7-term geometric series is:
-32766.
