Answer 1

Answer:

x = 21

Step-by-step explanation:

40, 38, 2 X + 10, 2 X + 1, 15, 11, 8, 5

Since there are 8 numbers the median is average of 4th and 5th terms. Also the numbers are arranged in descending order so we observe from last.

2x + 1 + 15/2 = 29

2x + 16 / 2= 29

=> x + 8 = 29

=> x = 21.
