一道我不知道叫什么类型的数学题find the accumulated value of an investment of $3750 for 7 years at an interest rate of 3.5%(rounded to the nearest cent),if the interest is:1) compounded semianually; 2) compounded quarterly; 3)compounded monthly; 4)continuously第四个我知道应该是3750*e^(0.035*7) 求前三题的答案.有为啥的话就说一下为啥吧

一道我不知道叫什么类型的数学题
find the accumulated value of an investment of $3750 for 7 years at an interest rate of 3.5%(rounded to the nearest cent),if the interest is:1) compounded semianually; 2) compounded quarterly; 3)compounded monthly; 4)continuously
第四个我知道应该是3750*e^(0.035*7)
求前三题的答案.有为啥的话就说一下为啥吧
答
1）先存进去 半年后把钱和利息取出来 再存进去 如此往复
2）每季度取出来一次
3）每月
1）（1+3.5%/2）^14
2）（1+3.5/4）^28
3) (1+3.5/12)^84
