1. The series sum of (n + 1/n) for integer values 1 = n = 4 is: a. 11 b. A rational real number c. A complex number d. An integer 2. If x is greater than five then y equals six and if x is less than two then y equals three can be represented as: a. y = 3 for x 5 b. 2 = x = 5 c. 2 > x d. xy/2 = 5y/6 3. The sum of two prime numbers is: a. Always odd b. Always a prime number c. Always even d. None of the above
