Answer:

25.5

Step-by-step explanation:

Mean and average are same

It can be answered by (n+1)/2

Solution:

To calculate the average: Sum of Elements/Number of Elements

The sum of Elements in this series can be calculated using AP (Arithmetic Progression)

If we have first term 1.

Last term n.

Common difference 1.

Thus,

ThesumofnNaturalNumbers=n(n+1)/2

So, answering the question average of first 50 natural numbers:

[(n(n+1)/2)/n]=(n+1)/2=(50+1)/2=61/2=25.5

Answer:

Heyy buddy, here's ur answer:

Mean=Sum of the numbers/Total number of numbers

Hence,

Sum of first 50 natural numbers=(50×51)/2=1275. Since sum of n consecutive numbers= (n(n+1))/2

Therefore,

Mean=1275/50=25.5

Hope it helps
