55 is not a prime number because you can do 5*11=55. The definition of a prime number is a number that has only the factors of 1 and itself. Because 55 has 1*55-55 AND 5*11=55 it is not a prime number. Hope that helps!!
59 is the first prime number after 55.
The prime numbers between 55 and 70 are 59, 61, and 67. A prime number is a number greater than 1 that can only be divided by 1 and itself without leaving a remainder. In this case, 59, 61, and 67 are the only prime numbers within the given range.

The prime numbers between 55 and 70 are: 59, 61 and 67
The odd composite numbers between 50 and 60 are 51, 55, and 57. Because all the primes are odd except for 2 and adding two odd numbers will result in an even number, one of the two prime numbers must be 2, which when added to an odd number will result in an odd number. So, we subtract 2 from each of these numbers and check whether it is prime. 51 - 2 = 49, which is not prime. 55 - 2 = 53, which is prime. 57 - 2 = 55, which is not prime. Thus, the number is 55, which can be written as 2 + 53.
55 = 5 * 11
