Study the following information and answer the questions that follow. A number series is given as 20, a, b, c, d, 65 Where a, b, c and d are missing terms. It is also given that: I. a – 20 = (x2 + y) II. The value of b is greater than a and the difference of b and a is equal to the [(x+1)^2+y] III. The value of c is [(x+2)^2 + y] more than b and the value of d is [(x + 3)^2 +y] more than c. Note: x is equal to the HCF of 2 prime numbers and the value of y is equal to the smaller root of the quadratic equation z^2 – z – 6 = 0 . What is the value of d?
