Q: In my manuscript, how should I use "etc." inside a parenthesis at the end of a sentence?

Detailed Question -

What's the proper structure for writing "etc." at the end of a sentence when it's at the end of a parenthesis phrase that is only part of the sentence?  Is the following correct?   "....(a,b,c, etc.)."

Answer:

When using "etc." in parenthesis, you should use it in the same way as you would use it in a regular sentence:

Example: I prefer healthy food such as fruits, vegetables, cereals, etc.

Now if you use "etc." in parenthesis at the end of a sentence, you will need to put a "period" after the parenthesis. 

Example: My roommate has burgers, pizzas, and carbonated drinks on a daily basis, but I prefer healthy food (fruits, vegetables, cereal, etc.).

Hope this helps.
