If x 1 ,   x 2 ,   x 3 . . . x 34 are numbers such that x i = x i + 1 = 150 ,   ∀ i ∈ 1,2 , 3,4 , . . . . 9 and x i + 1 - x i = - 2 ,   ∀ i ∈ 10,11 , . . . . 33 , then median of x 1 ,   x 2 ,   x 3 . . . . . . x 34 is

Options

  1. A134
  2. B135
  3. C148
  4. D150

Correct answer

B. 135

Step-by-step solution

Total no. of term = 34 So mean of 17 t h and 18 t h term is median x 10 + n = 136 , x 18 = 13 4 Hence, median = 135
