Dear student,

The solution for 2nd question is as follows :

The arithmetic mean, or simply the mean or average when the context is clear, is the sum of a collection of numbers divided by the count of numbers in the collection.

Sum of first n natural numbers = $\frac{n(n+1)}{2}$

Kindly post your other queries in a different thread.

Regards
