Answer:
Arithmetic = 3%
Geometric = 2.37%
Explanation:
The arithmetic average of 'n' returns is given by:

For five returns of 5% ,21%, -12%, 7%, and -6%:

The geometric average of 'n' returns is given by:
![G=\sqrt[n]{(1+r_1)*(1+r_2)*...*(1+r_n)}-1](https://tex.z-dn.net/?f=G%3D%5Csqrt%5Bn%5D%7B%281%2Br_1%29%2A%281%2Br_2%29%2A...%2A%281%2Br_n%29%7D-1)
For five returns of 5% ,21%, -12%, 7%, and -6%:
![G=\sqrt[5]{(1+0.05)*(1+0.21)*(1-0.12)*(1+0.07)*(1-0.06)}-1\\G=0.0237=2.37\%](https://tex.z-dn.net/?f=G%3D%5Csqrt%5B5%5D%7B%281%2B0.05%29%2A%281%2B0.21%29%2A%281-0.12%29%2A%281%2B0.07%29%2A%281-0.06%29%7D-1%5C%5CG%3D0.0237%3D2.37%5C%25)
