QUESTION 1 for Gradescope: For each of the following series (A-D), determine if it is a geometric series. If it is geometric, give the common ratio of successive terms. If it is not geometric, write NONE.   A)   7 + 14 + 21 + 28 + 35 + ⋯ {“version”:”1.1″,”math”:”\( 7 + 14 + 21+ 28 + 35 + \cdots \)”}   B)   z 4 + z 5 + z 6 + z 7 + z 8 + ⋯ {“version”:”1.1″,”math”:”\( z^4 + z^5 + z^6+z^7+z^8 + \cdots \)”}   C)   3 − 1 + 1 3 − 1 9 + 1 27 − 1 81 + ⋯ {“version”:”1.1″,”math”:”\( 3 -1 + \frac{1}{3} – \frac{1}{9} + \frac{1}{27} – \frac{1}{81} + \cdots \)”}   D)   1 + y 2 + y 2 4 + y 3 8 + ⋯ {“version”:”1.1″,”math”:”\( 1+\frac{y}{2} + \frac{y^2}{4} + \frac{y^3}{8}+ \cdots \)”}
