umm do u know the answer? cus i have arrived to one and i do not know if what i have done is right 😀

so i used some mathematics here and hopefully i have not broken any math rules -_-

this is what i came up with:

n = 10

3500= 500 [ 1- 1/(1+r)^10 / r all i did here was get read of that negative exponent by reciprocal.
3500= 500 [ (1+r)^10 – 1/ (1+r)^10 / r ] what i have done here is i have solved the numerator fraction part by finding L.C.D
3500= 500 [ -1/r ] we cancel out (1+r)^10
hence r = approx -7 and i dont know how to get rid of the minus 😀 If you substitute the r=7 you get approx 3511 well something close though don’t u think 😉

Cheers

the answer is : 7,07 % (7,07282 )

no direct formula.. must be simulate. but i can find interest rate easy with anything annuity case.. try me please with this topic.
