Answer:
-100
Step-by-step explanation:
The sum of the first 7 terms of the geometric series is 15.180
<h3>Sum of geometric series</h3>
The formula for calculating the sum of geometric series is expressed according to the formula. below;
GM = a(1-r^n)/1-r
where
r is the common ratio
n is the number of terms
a is the first term
Given the following parameters from the sequence
a = 1/36
r = -3
n = 7
Substitute
S = (1/36)(1-(-3)^7)/1+3
S = 1/36(1-2187)/4
S = 15.180
Hence the sum of the first 7 terms of the geometric series is 15.180

The closing price on Thursday was $25.69 and on Wednesday, it went down by 0.75. and it went down again by 0.75 which brought it to $25.69.
That would mean the closing price on Wednesday was $26.44 (25.69 + 0.75)
