[DTube] Geometric Sequences: Find the first term and common ratio
I'm in the process of uploading all of my Youtube videos to DTube, where they can be recorded on the Steem blockchain.
In this video, we use the general equation for terms of a geometric sequence:
tn = arn-1
to find the first term a, the common ratio r and the nth term of a geometric sequence for a known values of the third term (t3 = 100) and 5th term (t4 = 400).
