Question: The average of 7 consecutive numbers is n. If the next two numbers are included, the average will-

Solution:

The average of 7 consecutive numbers is n implies that the 4th term is equal to n.

Now if we include next two terms then the average of 9 terms will be the 5th term. Now as the terms are consecutive, so the 5th term will be n + 1.

(1 + 2 + 3 + 4 + 5 + 6 + 7)/7 = 28/7 = 4

(1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9)/9 = 45/9 = 5
