Question

find the median of 2x,2x+1,2x-1 where x>1​

Answer 1

n is odd. ( n means number of terms)

Median= vàlue of [(n+1)/2]th term

Mediàn= [(3+1)/2]th term = 2nd term

Rearrange these in ascending order

2x-1,2x,2x+1

second term = 2x

Therefore, Median= 2x

Note : if n is even

Median=meàn of the vàlues[(n/2)th term]ànd [(n/2 +1)th term]
