I asked a question in this post.
To illustrate this, I am trying to find a
concrete example
.let $(A_n)_{n=2}^\infty$ denote the sequence of sets $A_n$
where $A_n$ is the set of primes $\le n (n\ge 2)$.
$A_2={2},\ A_3={2,3},A_4=A_3,A_5={2,3,5},...$
where by "abstract", I mean the conceptual term sequence of sets
, by "concrete example", I mean ({2},{2,3},{2,3,5},...)
similarly, a number
is an example of "abstract", 1, 2, 0.5 are examples of the "opposite of abstract"
In this context, Is the opposite of abstract "concrete", "particular", "specific" or other word?
