Assume that 10 numbers = 200

What formula would I use to average (weight) these 10 numbers so that the
2nd number is 10% greater than the 1st, the 3rd number is 10% greater than
the 2nd, the 4th number is 10% greater than the 3rd, etc . . . and the
total
of 10 numbers will equal 200?

Im sure someone knows the answer!

Thanx in advance

Kevin
