Question

by how much is the average of the natural numbers from one to 50 more than the average of the natural numbers from 1 to 25​

Answer 1

Answer:

The average of natural numbers from 1 to 50 is is more than the average of natural numbers from 1 to 25 by 12.5.

Step-by-step explanation:

To find the sum of natural numbers from 1, 2,....49, 50 we can use

Sn = n(n+1)/2 where n = 50

Sn = 50(50 + 1)/2 = 1275

Average = 1275 / 50 = 25.5

Similarly,  

To find the sum of natural numbers from 1, 2,....24, 25 we can use

Sn = n(n+1)/2 where n = 25

Sn = 25(25 + 1)/2 = 325

Average = 325 / 25 = 13

So the difference between the two averages = 25.5 - 13 = 12.5
