Hi,
Find the genral term of the G.P with third term 1 and the seventh term 8?
Thanks!!!
Geometric Series
Btw, what does "genral" mean?
The general term of any geometric sequence is given by
Tn =
where clearly, is the first term and is the common ratio of the geometric progression.
So we have here,
T3=1
T7=8
i.e. ............(1)
and ............(2)
Divide (2) by (1) to eliminate a
so we have, = 8/1
so
