what is twin prime number? |
|
Answer» Twin Prime Numbers A Twin prime are those numbers which are prime and having a difference of two ( 2 ) between the two prime numbers. In other words, a twin prime is a prime that has a prime gap of two. Sometimes the term twin prime is used for a pair of twin primes; an alternative name for this is prime twin or prime pair. Usually the pair (2, 3) is not considered to be a pair of twin primes. Since 2 is the only even prime, this pair is the only pair of prime numbers that differ by one; thus twin primes are as closely spaced as possible for any other two primes. The first few twin prime pairs are : (3, 5), (5, 7), (11, 13), (17, 19), (29, 31), (41, 43), (59, 61), (71, 73), (101, 103), (107, 109), (137, 139), …etc. Twin prim numbers are those prime numbers that have difference 2 |

Answer» this poem says about the wind that there presence only can feel no one see the wind ..just like the humanity which can only be felt The poem opens with the title that asks, "Who has seen the wind?" The speaker informs us that neither she nor anyone else has ever seen the wind. But we do see the leaves "trembling," which informs us that the wind is passing through. The speaker then repeats the same question in the following stanza. The answer remains the same that no one has seen the wind, but when the trees "bow down their heads," we again realize that the wind is passing by. The first line of poem is who has seen the wind ? means no one can't see wind but we can feel its presence when leaves start trembling when they move by wind we can see their presence we can feel wind when tree starts to move in short no one can see wind neither you or I but we can feel it |
