某国采用养老储备金制度，公民在就业的第一年就交纳养老储备金，数目为a₁，以后第年交纳的数目均比上一年增加d（d>0），因此，历年所交纳的储备金数目a₁，a₂，…是一个公差为d的等差数列，与此同时，国家给予优惠的计息政策，不仅采用固定利率，而且计算复利，这就是说，如果固定年利率为r（r>0），那么，在第n年末，第一年所交纳的储备金就变为a₁（1+r）^n-1，第二年所交纳的储备金就变为a₂（1+r）^n-2，……，以T_n表示到第n年末所累计的储备金总额。

（1）写出T_n与T_n-1（n≥2）的递推关系式；

（Ⅱ）求证：T_n=A_n+B_n，其中{A_n}是一个等比数列，{B_n}是一个等差数列。

读下列材料和图，回答问题。

材料　从1949年起，近60年过去了；从1979年元旦《告台湾同胞书》首倡两岸“三通”以来，近30年过云了，然而浅浅的台湾海峡，却似难以跨越的鸿沟天堑。两岸不知道有多少颗忧伤的心，日日夜夜被思念牵动摧折；又不知有多少远眺的眼，朝朝暮暮为亲情望穿秋水。这一切，终于在2008年12月12日化作历史。银燕展翅，百舸争流，鸿雁传书——随着两岸空运、海运直航和直接通邮的同步实施，“三通”终于在这一天从梦想变成了现实。

When something goes wrong, it can be very satisfying to say, “Well, it’s so-and-so’s fault.” or “I know I’m late, but it’s not my fault; the car broke down.” It is probably not your fault, but once you form the habit of blaming somebody or something else for a bad situation, you are a loser. You have no power and could do nothing that helps change the situation. However, you can have great power over what happens to you if you stop focusing on whom to blame and start focusing on how to remedy the situation. This is the winner’s key to success.

Winners are great at overcoming problems. For example, if you were late because your car broke down, maybe you need to have your car examined more regularly. Or, you might start to carry along with you the useful phone numbers, so you could call for help when in need. For another example, if your colleague causes you problems on the job for lack of responsibility or ability, find ways of dealing with his irresponsibility or inability rather than simply blame the person. Ask to work with a different person, or don’t rely on this person. You should accept that the person is not reliable and find creative ways to work successfully regardless of how your colleague fails to do his job well.

Being a winner is all about creatively using your skills and talents so that you are successful no matter what happens. Winners don’t have fewer problems in their lives; they have just as many difficult situations to face as anybody else. They are just better at seeing those problems as challenges and opportunities to develop their own talents. So, stop focusing on “whose fault it is.” Once you are confident about your power over bad situations, problems are just stepping stones for success.
