Answer 2

Answer:

A=null set=ø

Step-by-step explanation:

Given that,

A={b/b€N,2b+1 is even}

now, Consider 2b+1

let, b=1

=>2(1)+1=3=odd

let,b=2

=>2(2)+1=5=odd

so, this sequence is showing that '2b+1' is an odd number not an even number.

therefore,

the given set A={b/b€N, 2b+1 is  even number} is a null set (ø)
