- Assume a generic recursive relation is defined as : A[i] = p*A[i-1] + q where p and q are coefficients of the relation. Write a function that takes the first three numbers in this relation as a list, such as [A[0], A[1], A[2]] and computes p and q, and returns A[3]. For example, given [1,3,5] your function should return 7, because the numbers 1,3,5 are produced by the series: A[i] = A[i-1] + 2 where p is 1 and q is 2, and then the next number in the series becomes 7. You can assume that p and q are always integers. You can also assume that p and q are determinable in any test case.

- Suppose 1,000 Integer elements are generated at random and are inserted into a sorted linked list and a binary search tree (BST) separately. Considering the efficiency of searching for an element in the two structures, which of the following statements is true? The search operation on the list takes longer time because the numbers are not sorted. The search operation will take the same time in both structures. The search operation on the BST takes shorter time because it is relatively balanced. None of these. The search operation on the BST takes longer time because the numbers are not sorted.Assume a generic recursive relation is defined as :A[i] = p*A[i-1] + qwhere p and q are coefficients of the relation.
