A geometric gradient has a positive cash flow of $1,000 at EOY zero (now), and it increases

Question:

A geometric gradient has a positive cash flow of $1,000 at EOY zero (now), and it increases 5% per year for the following five years. Another geometric gradient has a positive value of $2,000 at EOY one and it decreases 6% per year for years two through five. If the annual interest rate is 10%, which geometric gradient would you prefer?
