The arithmetic mean of the 5 consecutive integers starting with 'p' is 'q'.
(p + p + 1 + p + 2 + p + 3 + p + 4)/5 = q
5p + 10 = 5q
p + 2 = q
the arithmetic mean of 9 consecutive integers that start with p + 2 = 5p + 10 = 5q
P + 2 = q
Now 9 consecutive number starting from p + 2 that means start from q
= (9q + 36)/9
= q + 4. ans
