There are eight twin primes between 1 and 100. They are (3, 5), (5, 7), (11, 13), (17, 19), (29, 31), (41, 43), (59, 61), and (71, 73).
{3,5},{5,7},{11,13},{17,19},{29,31},{41,43},{59,61},{71,73}
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.
25. any number in half equals how many twin primes. so 50/2 =25 EX.1-2 =1 1-10 = 5

There are only two consecutive numbers that are primes, namely 2 and 3. Otherwise there is always a gap of at least 2; two primes separated by a gap of exactly 2 (eg 3 and 5) are known as twin primes. If you are wanting to know what the twin primes between 1 and 200 are, then they are: {3, 5}, {5, 7}, {11, 13}, {17, 19}, {29, 31}, {41, 43}, {59, 61}, {71, 73}, {101, 103}, {107, 109}, {137, 139}, {149, 151}, {179, 181}, {191, 193}, {197, 199}.
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 fifteen. (3,5)(5,7)(11,13)(17,19)(29,31)(41,43)(59,61)(71,73)(101,103)(107,109)(137,139)(149,151)(179,181)(191,193)(197,199)
2 21 3 31 4 41 4 41...
Any number greater than one can be co-prime. I guess the answer is 49.
