The set-builder form of the set A={12,14,18,116,132,164} is ___.
{x:x=12n, where n∈N and n≤6}
Given the set A={12,14,18,116,132,164}
={121,122,123,124,125,126}.
We can see that the denominators of the fractions in the set can be represented by 2n, where n∈N and n≤6.
So,the set builder form of A is
{x:x=12n, where n∈N and n≤6}
