Geometric Sequences: Find the first term and common ratio
In this video, we use the general equation for terms of a geometric sequence: t_n = ar^(n-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 (t_3 = 100) and 5th term (t_4 = 400). Thanks for watching. Please give me a "thumbs up" if you have found this video helpful ...
