[DTube] Geometric Sequences: Find the 4th term given the 7th term

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:

t_n = ar^n-1

to find the 4th term of a geometric sequence for a known value of the first term (a = 6) and 7th term (3/32).
