请问老师，这道题目是不是有误？老师讲PVRI(t-1)=RI(t-1)xW/1+r-W
=1.98x0.7/1+10%-0.7. 我在想是不是李老师说的特别情况，当RIt不等于RI(T-1)x(1+g) 是就直接用RIt. 谢谢解答

T不是应该代表进入到第二段时间的时间吗？这道题的T难道不应该是2015吗？跟2016又有什么关系呀？2.我理解的是，下面黑色打印的这个公式T-1对应的就是2014年，用RI 2015计算对应2014年年底的PVRI然后折3年回去（也就是老师的红字部分），这个没问题。但是老师的解析我看写的“如果要使用李老师的公式，则需要向后推导一年，计算出RI2016以后才可以使用，并且折现的PVRI就会落在2015年年末，需要和2015年的RI=1.608一起折现4年到0时刻，就可以获得和本题一样的答案了”。这跟2016年有什么关系呢？如果2016年的话，不应该是RI(T+1）吗？既然是红色公式再向后一期推导出来的
