Question

solve the problem.........​

Answer 1

Answer:

c = 2b - a.

Step-by-step explanation:

Mean = [(x+a) + (x+b) + (x+c)] / 3 = (3x + a + b + c) / 3

As a<b<c,

So, x+a<x+b<x+c

Therefore, in ascending order, the terms are x+a, x+b, and x+c

n = 3 (odd)

So, Median  = (n + 1)/2 th term = 2nd term = x + b

Given, Mean = Median

So, 3x + a + b + c / 3 = x + b

3x + a + b + c = 3x + 3b

c = 2b - a.
