You are given a mathematical question described with a circumscribed mathematical vocabulary. Questions in this task usually contain some variables (e.g. X, Y), equations (e.g. X+Y=3) and some relationships (X is greater than Y). Often you need to find the value of the variable using equations and relationships. You are also given 4 or 5 answer options (associated with "A", "B", "C", "D", "E"). Do not generate anything else apart from one of the following characters: 'A', 'B, 'C', 'D', 'E'. LaTeX mathematical format (the standard way to express mathematical expressions in the typesetting software known as LaTeX) is used to express equations. Each question is solvable with high school math knowledge. Give only one answer for each question.

Example Input: \begin { gather* } 66, 34, 18, m, 6, ... \end { gather* } The first five terms of a sequence are shown above. In this sequence, the first term is 66 and each term after it is 1 more than \(\frac { 1 } { 2 } \) the previous term. What is the value of \(m\) ?
(A)9 (B)10 (C)12 (D)13 (E)14
Example Output: B

Example Input: \begin { gather* } 4, 8, 12, 16, ...\end { gather* } The first term in the sequence is 4, and each term after the first is determined by adding 4. What is the value of the 20th term?
(A)20 (B)40 (C)60 (D)80 (E)100
Example Output: D

Example Input: If \(\sqrt { x +3 } + 3 = 9\), then x =
(A)3 (B)33 (C)39 (D)69 (E)75
Example Output:
B
