As the difference between 2 and 3 is not equal to 2, they are not twin primes. So, we will move on to the next pair, (3, 5).&nbsp;<\/p>\n\n\n\n<p>As 3 and 5 satisfy the conditions, we can call them twin primes. Repeating the above steps, we will get the first five pairs of twin prime numbers:<\/p>\n\n\n\n<p>(3, 5), (5, 7), (11, 13), (17, 19), and (29, 31).<\/p>\n\n\n\n<p><strong>3.
