Answer:
B) 2
Step-by-step explanation:
The first differences are increasing by 1 from term to term:
8-12 = -4
5-8 = -3
3-5 = -2
2-3 = -1 . . . . . if the next term is 2, as we believe it should be.

<em>Comment on number sequences</em>
Any finite length sequence of n numbers can be modeled exactly by an n-1 degree polynomial. That is, a 4th-degree polynomial can be made to describe the sequence regardless of the next term you may choose.
If you choose the next term to be 2 as we suggest, then the sequence can be modeled by a 2nd-degree polynomial ...
(n² -11n +34)/2 . . . . for n = 1, 2, 3, ...
It is D because us the given equation all you do is plug in the x values given on the chart
The box-and-whisker plot of the data, showing the five-number summary, is shown in the image atatched below.
<h3>What is the Box-and-whisker Plot?</h3>
The box-and-whisker plot is a plot that displays the minimum, maximum, median, lower and upper quartile of a data, which is termed as the five-number summary of a data.
Given the data, 20, 23, 28, 14, 13, 24, 18, 11, find the five-number summary:
- Minimum - 11
- Lower Quartile - 13.5
- Median - 19
- Upper Qaurtile - 23.5
- Maximum - 28
Therefore, the box-and-whisker plot of the data, showing the five-number summary, is shown in the image atatched below.
