几道关于数列的中职数学题 大家帮帮忙好么 要 详细点的解答过程
1.设数列{an}为公比为q的等比数列,它的前n项和为Sn,若数列{Sn}为等差数列,求q的值
2.在等比数列{an}中,a₁=81,a5=16.求q和Sn
3.在等差数列{an}中,a₁,a₄,a25 三个数依次成等比数列,且a₁+a₄+a25=114.求这三个数
4.已知数列{an}满足log₂（Sn+1）=n(n∈N*),其中Sn为{an}的前n项和,求证：数列{an}为等比数列
5.已知等差数列{an}的公差d≠0,且a₁,a₃,a9成等比数列 求a₁+a₃+a9/a₂+a₄+a10的值
6.已知一个项数是偶数的等比数列的首项为1,其奇数项的和为85,偶数项的和为170,求这个数列的公比和项数

Thanksgiving Day is a very special day for people in the United States.They celebrate it on the last Thursday in November.Canadians also celebrate Thanksgiving Day,but they do it on the second Monday of October.In Britain,where this festival is called "Harvest Festival",people celebrate it earlier in the year,in September.
The first thanksgiving service (仪式) in North America took place on December 4th,1619 when 38 English people arrived in America to make their home in the new country.They held this service not to thank God for the harvest,but to thank God for their safe journey.The next year,many more English people arrived.They had a bad winter,but fortunately the harvest was good.They decided to celebrate it with a big meal.They shot and killed small animals to eat and cooked everything outside on large fires.About 90 Indians also came to the meal.Everyone ate at tables outside their houses and played games together.The festival lasted three days.
A Thanksgiving Day celebration was held every year for a long time,but not always on the same day of the year.Then,in 1789,President George Washington named November 26th as the Day of Thanksgiving.In 1863,President Abraham Lincoln changed the date,and said that the last Thursday in November should be Thanksgiving Day.
