Here are all the twin primes between 100 and 200.(101, 103), (107, 109), (137, 139), (149, 151), (179, 181), (191, 193), and (197, 199).Twin primes are prime numbers that differ from each other by 2.

False. Co-primes are not the same as twin primes.Co-primes are any numbers having no common factorsother than 1. Examples of co-primes are 8 and 9 or 15 and 32.Twin primes are pairs of prime numbers exactly 2 apart such as 11 and 13 or 659 and 661.

The twin primes (those with a difference of just 2) up to 1000, are as follows:3, 55, 711,1317, 1929, 3141, 4359, 6171, 73101, 103107, 109137, 139149, 151179, 181191, 193197, 199227, 229239, 241269, 271281, 283311, 313347, 349419, 421431, 433461, 463521, 523569, 571599, 601617, 619641, 643659, 661809, 811821, 823827, 829857, 859881, 883The first twin primes after 1000 are 1019 and 1021.

False. Co-primes are not the same as twin primes.Co-primes are any numbers having no common factorsother than 1. Examples of co-primes are 8 and 9 or 15 and 32.Twin primes are pairs of prime numbers exactly 2 apart such as 11 and 13 or 659 and 661.

Not true. 2 + 3 = 5, where all three are primes. One of the primes in the sum must be 2, otherwise both primes would be odd and their sum would be even (and >2) and therefore not prime. Such primes: p and p+2 [3 and 5 in the above example] are known as twin primes and there are infiitely many twin primes.

There is no known prime formula to identify all primes. There are some formulae that work only for some classes of primes. Mathematicians have

Twin primes are pairs of prime numbers that differ from each other by two. Examples of all twin primes less than 100 are (3, 5), (5, 7), (11, 13), (17, 19), (29, 31), (41, 43), (59, 61), and (71, 73).

The twin primes between 1 and 100 are (3, 5), (5, 7), (11, 13), (17, 19), (29, 31), (41, 43), (59, 61), (71, 73).

There are an infinite number of pairs of prime two apart, classified as "twin primes". For lists, see the link.
