Make a list of seven consecutive numbers, none of which is prime.

Two consecutive numbers are/are not co-prime

State true (T) or false (F): The sum of primes cannot be a prime. The product of primes cannot be a prime. An even number is composite. Two consecutive numbers cannot be both primes. Odd numbers cannot be composite. Odd numbers cannot be written as sum of primes. A number and its successor are always co-primes.

The sum of two consecutive numbers is 53. Find the numbers.

Write seven consecutive composite numbers less than 100 so that there is no prime number between them.

Write seven consecutive composite numbers less than 100 so that there is no prime number between them.

A 2n digit number starts with 2 and all its digits are prime, then the probability that the sum of all 2 consecutive digits of the number is prime is a. 4xx2^(3n) b. 4xx2^(-3n) c. 2^(3n) d. none of these

The product of 2 distinct positive prime numbers is an even number, and one less than the product is a prime number. All of the following prime numbers could be one of the original prime numbers EXCEPT ?
