初中第七周数学试卷答案
一、选择题（每题5分，共25分）1. 已知a、b、c是等差数列的前三项，且a+b+c=21，a+c=13，则b的值为：A. 7B. 8C. 9D. 10答案：A解析：由等差数列的性质可知，a+c=2b，代入已知条件得2b=13，解得b=6.5。
但题目要求的是整数解，故排除选项C和D。
将b=6.5代入a+b+c=21，得a+c=14.5，与a+c=13矛盾，故排除选项B。
因此，正确答案为A。
2. 若方程x^2-4x+3=0的两根为a和b，则a+b的值为：A. 4B. 5C. 6D. 7答案：B解析：根据韦达定理，方程x^2-4x+3=0的两根之和为4，即a+b=4。
因此，正确答案为B。
3. 若等比数列的前三项分别为2、4、8，则该数列的公比为：A. 1B. 2C. 3D. 4答案：B解析：等比数列的公比定义为相邻两项的比值，即q=a2/a1。
将前三项代入得q=4/2=2。
因此，正确答案为B。
4. 若一个等差数列的前n项和为S，首项为a1，公差为d，则S与n的关系为：A. S=n^2B. S=n(n+1)C. S=n(a1+an)/2D. S=n(a1+an)答案：C解析：等差数列的前n项和公式为S=n(a1+an)/2。
因此，正确答案为C。
5. 若方程2x^2-3x+1=0的两根分别为a和b，且a+b=3，则ab的值为：A. 2B. 1C. 0D. -1答案：A解析：根据韦达定理，方程2x^2-3x+1=0的两根之积为ab=1/2。
将a+b=3代入得a^2+2ab+b^2=9，即(a+b)^2=9，解得ab=2。
因此，正确答案为A。
二、填空题（每题5分，共25分）6. 若等差数列的前三项分别为2、5、8，则该数列的公差为______。
答案：3解析：等差数列的公差定义为相邻两项的差，即d=a2-a1。
将前三项代入得d=5-2=3。
因此，正确答案为3。
7. 若等比数列的前三项分别为2、4、8，则该数列的公比为______。

1.分析：用这四个数组成比例，有三种情况，即a 与这三个数中的任意一个数同时作为内项或外项。
解答：（1）4a=4.8×12，解得a=14.4 ；（2）4.8a=4×12，解得a=10 ；（3）12a=4.8×4，解得a=1.6.
2.解：设需要药粉x 千克。
X ： 1500=1:500
X=3
3.（1） 2 50 25 10 10 30
（2）成反比例 因为平均每辆车运的质量与所需车辆的数量是相关联的量，
平均每辆车运的质量变化时，所需车辆的数量也随之变化，且它们的乘积是一定的，所以它们成反比例。
（3）150÷5=30（辆）。
