Question

      for an observation X and X + 1 and X + 1 and X + 2 If mean is equal to mode then find the value of median​

Answer:

$∵ nx 1​ +x 2​ .....+x n​ ​ = xˉ .......... (i)∴ Req. sum =(x 1​ − xˉ )+(x 2​ − xˉ )+......+(x n​ − xˉ )=(x 1​ +x 2​ +......x n​ )−n xˉ =n xˉ −n xˉ =0 (from eq. (i))$
