I can't really answer that. Sorry. But I know a YouTube account that can help you. Search up L. Moon and it will show you a list of videos.
Answer:
it is reflected across the Y axis
The sum of the amounts of change in the bacteria after the seventh day is 6554.
<h3>What is the geometric sequence about?</h3>
The sequence are:
2, -8, 32, -128
Note that a first term of:
(a) of 2
A common ratio (r) of -8/2 = -4.
So the sum of n terms is said to be:
Sn = a1·(r^ n -1)/(r -1)
For the given sequence, the sum of 7 terms is said to be:
S7 = 2·((-4)^7 -1)/(-4-1)
= 2(-16384/-5)
= 6554
Therefore, The sum of the amounts of change in the bacteria after the seventh day is 6554.
