高考中的数列问题
考点自测
数列<Object: word/embeddings/oleObject1.bin>
是公差不为0的等差数列，且
<Object: word/embeddings/oleObject2.bin>
为等比数列
<Object: word/embeddings/oleObject3.bin>
中连续的三项，则数列
<Object: word/embeddings/oleObject4.bin>
的公比为（ ）
<Object: word/embeddings/oleObject5.bin>
B.4 C.2 D.
<Object: word/embeddings/oleObject6.bin>
已知等差数列
<Object: word/embeddings/oleObject7.bin>
的前<Object: word/embeddings/oleObject8.bin>
项和为<Object: word/embeddings/oleObject9.bin>
，<Object: word/embeddings/oleObject10.bin>
，则数列
<Obje ...
