'Inside' is a strange word to use for a city. If something is 'inside' something else, it is completely enclosed on all sides, as if it were inside a bag or a box. If you simply mean 'I grew up living in the city', then you can just say that.

"Inside" means something in something like "A ball inside a box". Your sentence is incorrect and you should change the preposition "inside" and use "in"

Hi Nancy, It looks correct to me
