This question already has an answer here:
I am wondering if a single article can be used for two nouns.
I came across an article on NY Times, and encountered one single indefinite article used for two nouns.
Despite changing sexual mores, it's clear that many men and women still expect the man to pay, particularly on a first and second date. That seems to be especially true outside the Northeast, where sex roles remain more traditional.
One article for two nouns is possible? Why not writing it again for the second noun? Like - "....particularly on a first date and a second date. That seems..."
Based on this, I want to say
"A first and a second layer" or "a first layer and a second layer"
"A first and second layer"
Is that okay?
