Answer 2

The first  11  positive integers form an arithmetic sequence with initial term  1 and common difference 1.

The sum of a contiguous sub sequence of an arithmetic sequence is the number of terms multiplied by the average of the first and last term.

In our case, there are  11  terms, with average value will be,

=> (1 + 11)/2

=> 12/2

=> 6

Thus, Mean of 11 positive numbers = 6.
