(3)526
(4) 263
The average of first primen​

Answer 1

Answer:

263

Step-by-step explanation:

Average of n natural numbers = [(n(n+1))/2]/number of observations

n(n+1)/2 = 525×526/2

= 138075

Average of all 525 natural numbers = 138075/525

=263

Answer 2

Answer:

We know that sum of first n natural numbers = n(n+1)/2.

Then the sum of 525 natural numbers = 525(525 +1)/2

= 525 * 526/2

= 138075.

The average of natural numbers till 525 = 138075/525

263.
