Please reverify the question, I think you have done some typo :)

This one should be solved by solving for the inequality on both sides.

1<5+5n<25
Subtract 5 from both sides, then divide by 5 on both sides.
That leaves you with this:

-4/5<n<4

So the integers that fall in that range are 0,1,2,3

Hope that helps
