Open in App
Solution

Set B is a null set because for every natural number b,(2b+1) is an odd number.
Let's take one example,
After putting b=3 in 2b+1 we get 2(3)+1=7,which is a odd number.
Let's take another example, after puttingb=7 in2b+1 we get 2(7)+1=15which is an odd number.
Hence, B is a null set for every natural number.
