Question

the following numbers 4, 7, x+1, x+3, x+4 , 14, 16 are arranged in ascending order and their mean and median value are the same, then the value of x is :​

Answer 1

Answer:

x= 7

Step-by-step explanation:

mean = median

sum of all terms/ number of terms = (n+1)/2 th term

(3x+49)/7 = 4th term

$\frac{3x + 49}{7} = x + 3$

3x + 49 = 7x + 21

4x = 28

x=7
