Question

the median of an observation are increasing order is 26 find the value of x if 10, 17, 22, x+2, x+4, 30 36 40 are observations

Answer 1

Median is middle most value or mean of middle most values depending on number of observations (odd/even)

So, median of given observations is [ (x+2) + (x+4) ]/2 = x+3

x+3 = 26

⇒x=23
