[DTube] Modelling Price Inflation with Geometric Sequences

I'm in the process of uploading all of my Youtube videos to DTube, where they can be recorded on the Steem blockchain.

You may have noticed that prices of goods and services, such as a cup of coffee gradually increase over a long period of time. This is a symptom of "inflation". It is a fact of life in a stable, steadily growing economy.

Of course one of the downsides is that the purchasing power of the currency in your wallet decreases over time, which is one of the reasons why governments try to limit the rate of inflation.

In this video, we track the price of a typical cup of coffee, assuming a constant target rate of inflation of 2% and find out how much it will cost in 10 years, and how long it will take for the price to double, with the help of geometric sequences.
