WebIn all the odd square numbers, one of the prime numbers for the solution is a 2. However, the square number 1 breaks the pattern and can't be made with any prime numbers. This is because an odd square number can be made from an odd and even prime but 2 is the only even prime number. Here are the solutions we have found: 2 + 2 = 4 7 + 2 = 9

Web9 Sep 2024 · Primes as sums of Fibonacci numbers. The purpose of this paper is to discuss the relationship between prime numbers and sums of Fibonacci numbers. One of our main results says that for every sufficiently large integer there exists a prime number that can be represented as the sum of different and non-consecutive Fibonacci numbers. WebExplanation: A prime number is a positive integer greater than 1 that has no positive integer divisors other than 1 and itself. The smallest prime number is 2, because it is the only even number that is prime. All other even numbers are divisible by 2 and therefore not prime. The other options are not correct.
