If `x-1` is an even number, which is the next even number?

Find the number of two digit even numbers?

Write the sequence of even numbers.

n is an even number. Write the previous number and the next number.

If A = {x:x is a natural number},B = {x:x is an even natural number}, C = {x:x is an odd natural number} and D = {x:x is a prime number}, find A cap B

If A = {x:x is a natural number},B = {x:x is an even natural number}, C = {x:x is an odd natural number} and D = {x:x is a prime number}, find A cap C

If A = {x:x is a natural number},B = {x:x is an even natural number}, C = {x:x is an odd natural number} and D = {x:x is a prime number}, find A cap D

If A = {x:x is a natural number},B = {x:x is an even natural number}, C = {x:x is an odd natural number} and D = {x:x is a prime number}, find B cap C

If A = {x:x is a natural number},B = {x:x is an even natural number}, C = {x:x is an odd natural number} and D = {x:x is a prime number}, find B cap D
