The average of five consecutive positive integers is n. If the next two integers are also included. the average of all these integers will 

Let the five consecutive integers be

$x+2,x-1,x,x+1$ and $x+2$

$\therefore$ Average = x.

Average after adding next two numbers

$=\frac{5x+x+3+x+4}{7}=x+1$

$\therefore$ Increases by 1.
