Use the normal geometric progression and substitute the values you have
Term 2 = 375;
Term 5 = 81;
SO now you have to simultaneous equations
Can be solved
Hi all
Theres this question about a geometric series that i can't figure out.
It says the second term is 375 and the fifth term is 81 and you have to show that the common ratio of the series is 0.6
I can't get the right answer :S
Thanks for the help x
