Solution to General Math Problems. Problem G1. Let n 4 be an integer. We wish to arrange the numbers 1, . . . , n in a circle so that any two consecutive numbers sum to a prime number. For example, (1; 2; 3; 4) would be a valid arrangement when n = 4. Is there an odd n. For each of n = 6, 5 for which this is possible?

A prime number (or prime integer, often simply called a "prime" for short) is a positive integer that has no positive integer divisors other than 1 and itself. More concisely, a prime number is a positive integer having exactly one positive divisor other than 1, meaning it is a number that cannot be factored.

What Are Prime Numbers? Prime numbers are numbers greater than 1 that only have two factors, 1 and the number itself. This means that a prime number is only divisible by 1 and itself. If you divide a prime number by a number other than 1 and itself, you will get a non-zero remainder.
