To find:
- 66th term of the arithmetic sequence -28, -45, -62, ...
Solution:
- First term (a) = -28
- Comman difference (d) = -45 - (-28) = - 17
- n = 66
Using formula:
Substituting values in the formula:
Hence,
- <u>66th term</u> of the arithmetic sequence is -<u>1133</u>.
<h2>
Answer:</h2>
The description that match the type of measure is:
Measure of center-- She found the middle value after arranging all the values from least to greatest.
Measure of variation of this data -- She found the mean and then found the average deviation of the weights from the mean.
<h2>
Step-by-step explanation:</h2>
As we know that the median of the data is the central tendency of the data and exist in the middle of the data.
Hence, the measure for the center of data is: Median.
and it is calculated by arranging the data in ascending or descending order and taking the middle value.
Also, we know that MAD of data or mean absolute deviation is used to tell the variation in a data set.
and the steps to calculate it is:
- Find the absolute deviation of data points from the mean.
- Calculate the mean of these absolute deviation.
