Question

the numbers 2,3,4,4,2x+1,5,5,6,7 are written in ascending order. if the median is 5, find the value of x . hence, find mode.

Answer 1

Median is middle term.
Median =5
2x+1=5
x=2

Mode means average
Mode = Sum of all observations/Number of observations
Mode = (2+3+4+4+5+5+5+6+7)/2
Mode = 17

Answer 2

Median is middle value
2x+1=5
2x=5-1
2x=4
x=2
Mode is sum of all observation
Mode=2+3+4+4+2+5+5+6+7
=38
