可以再解析下原理吗？

NO.PZ2018111302000003 问题如下 In orr to value a property with constant growth rate in income anvalue using F metho analyst collects below F assumptions: Going-in crate is 5.5%, termincrate is 6%, scount rate is 7.25%, what’s the growth rate of the target property? 0.50% 1.25%. 1.75%. C is correct.考点F assumption解析被投资房地产的收入和价值都是一致的增长率，等于折现率scount rate (7.25%) – 现行的资本化率going-in crate (5.50) = 1.75%. 为什么用Going-in crate，而不是termincrate？考试时，可否看到constant growth rate 就用Going-in crate？

NO.PZ2018111302000003 问题1题目最后只问了growth rate是多少，我怎么知道问的是一阶段的g还是二阶段的g？ 问题2r0（0时刻的回报率）和rn（n时刻求终值的回报率）是可能因为风险不同，而不同吧？那题目直接只说“the requirerate of return”，我怎么知道是给的啥时刻的回报率？ 问题3g0和gn可能会不同吗？ 问题4如果g0和gn不同（照题目来看是不同的），那为什么题目一开头还能将这个资产的growth rate描述成“constant”？
