The mean of consecutive positive integers from 2 to n

The mean of a set of consecutive integers can be found using the formula:
Mean = (First Term + Last Term) / 2

In this problem, the consecutive positive integers are from 2 to n.

• The first term is 2.
• The last term is n.

Substituting these values into the formula:
Mean = (2 + n) / 2
Mean = (n + 2) / 2

Answer:

The correct option is (A) (n+2)/2.
