!PLEASE ANSWER ASAP!

seats in a theater are curved from the front row to the back. the front row has 10 chairs, the second has 16 and the third has 22, and so on.

1. write a recursive rule for this series:

2. write an explicit rule for this series:
* if you simplify, please show all of the steps

3. using the explicit formula, find the number of chairs in row 5 (show your work):

4. the auditorium can hold 17 rows of chairs. write a sigma notation for this series, and then use either series formula to calculate how many chairs can fit in the auditorium.

see below

step-by-step explanation:

7.   there are 10 data points in the set.   the middle point is between 5 and 6.   the middle point in the top half is 8   and the middle point in the bottom half is 3. to find the iqr , take point 8 and subtract point 3

mid term   point 8 = 100   point 3 = 88

iqr = 100-88 = 12

final   point 8 = 93   point 3 = 78

iqr = 93 - 78 = 15

the final has the greatest iqr

6.   b - there is a high data value that causes the data set to be asymmetrical for the males: the data for males are high and asymmetrical .   there is an outlier for the males that skews the data

5.   the   iqr is a better measure of spread for the movies and basketball games.   since the basketball game has an outlier, we do not want to use standard deviation for measurement.  

3.   the exam median is much higher than the class median.   the median line is farther to the right on the exams

2.   there is no way to tell what the means are from the box and whisker plots.
