Question

if the mean of first 'n' natural number is 5x/9 then x
​

Answer 1

Answer:

Given that the mean of first n natural numbers = 5n/9.

We know that mean of n natural numbers = (x + 1)/2.

(x + 1)/ 2 = 5x/9

9(x + 1) = 2(5x)

9x+ 9 = 10x

9 = x

Answer 2

X = 9

Step-by-step explanation:

Given: Mean of first n natural numbers = 5x/9.

To find: X

Formula to calculate the mean of n natural numbers = (x + 1) / 2.

So we get (x + 1) / 2 = 5x / 9

9 (x + 1) = 2 * (5x)

9x + 9 = 10x

9 = x

Hence solved.
