Eighteen pairs of measurements were taken at random to estimate the relationship between variables X and Y. A least-squares line
was fitted to the collected data. The resulting residual plot is shown. A residual plot is shown with 18 points scattered above and below the x-axis in such a way that the distance from the x-axis increases as you move from left to right. Which of the following conclusions is appropriate?

Answer:
The terms listed are 8, 4, and 2 in that order. From what we can see, it is a geometric sequence whose next term is gotten by dividing the previous term by 2. The formula for finding the nth term of a geometric sequence is given as , where
a = first term which is 8
r = common ratio, 1/2 or 0.5
n = is the term we're looking for, 5
Putting all these together into one solid equation, we have
8 * =
8 * =
8 * 0.0625 = 0.5
Therefore, the 5th term of the sequence is 0.5. Similar example can be seen here brainly.com/question/9300199
