Sounds like a school assignment.
The average of the logarithmic values of a data set, converted back to a base 10 number is how to generate a geometric mean.
1. for each element, generate the log - use the log() function. Keep a running total of the log values.
2. divide the running total by n
3. convert the resulting "average" log value base to a base 10 number - exp(avg log value) gives that.
