What odd composite number between 50 and 60 can be written as the sum of two prime numbers?
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.
Is 55 an even number?
no because a full number would be divisible by 2, in this case it is not. Hints: If the final digit is odd the full number is odd. If it is even or 0, the whole number is divisible by 2: if 0 the answer will end in 5.
What is the sum of the first 55 consecutive odd numbers?
The sum_of_a_series = 1/2 x number_in_series x (first_number + last_number) The first odd number is 2 x 1 - 1 = 1, the 55th odd number is 2 x 55 - 1 = 109 Sum = 1/2 x 55 x (1 + 109) = 1/2 x 55 x 110 = 552 = 3025 It can be seen that the sum of the first n consecutive odd numbers is always n2: sum = n/2(1 + (2n - 1)) = n/2(2n) = n2
