The sequence {an} is an equal ratio sequence composed of real numbers, Sn = a1 + A2 + +An, then () A. Any term is not 0b. There must be one term that is not 0C. At most, there are finite terms that are 0d. Or none of them is 0, or there are infinite numbers that are 0

If an = (- 1) n + 1, when n is even, Sn = 0; if an = 2n & nbsp;, none of them is 0, so D
