What is the median for the set of data? 1 3 3.5 4

The median is 3.25

Step-by-step explanation:

First put the data in order from smallest to largest

1 3 3.5 4

The median is the middle of the data

1 3     3.5 4

It falls between 2 data points so take the average of those two data points

(3 + 3.5)/2

6.5 /2 = 3.25

The median is 3.25

arithmetic sequence

step-by-step explanation:

given that a sequence has terms as

19, 15, 11,

this is represented on a graph

the pattern indicates that the sequence is an arithmetic sequence with i term

a=19 and common difference d =-4

any general term

thus the sequence is reduced by 4 for each successive term starting from 1 and nth term is

24-5n.

first negative term would start after 5th term

5th term =24-25< 0

from 5th term onwards the sequence would be negative.
