We're not here to complete your homework.

This is where being able to subnet quickly can help you. Take the summarization address and find the range - then simply see which 2 address fit in the range. 192.168.176.0/21 would cover 192.168.176.0 through 192.168.183.255. And as an old math professor used to tell me, the rest is QED (Latin for finish it yourself)...

You should master subnetting before you bother with summarization. In your question, find the increment and you have your answer. The increment would be 8 in the 3rd octet.

Networks would be...

192.168.176.0
192.168.184.0

So any packet with an address between 192.168.176.1 and 192.168.183.254 will match.
