Hi there, for this question. I found the answer in excel sheet to be negative. is ther something wrong with my calculation:

Using the approach covered in your textbook calculate the geometric average annual rate of return over five years given the following annual rates, year 1 = 5.10%, year 2 = 4.95%, year 3 = 4.83%, year 4 = 4.75% and year 5 = 4.70% . What is the arithmetic average? Explain the difference.

(Rates as a percentage accurate to one basis point)

By adding and multiplying all 5 years of annual rates	1.27
5th root for the annual rates	-0.746369514
Year	Percentage	Adding 1 to avoid negative in Geometric Rate of Return)
1	0.0510	1.0510
2	0.0495	1.0495
3	0.0483	1.0483
4	0.0475	1.0475
5	0.0470	1.0470

Would like you to help me explain on this question
