Thread: Sequences

OKay so i did not get this question. And i will appreciate it if someone tells me how to do it.

use the given two terms of each geometric sequences to write the expression to the nth term:

Term 4 = 45 Term 6= 180

There is some application involved and it involves linear systems.

So thanks!

the nth term of a geometric series is given by: for

where is the first term, and is the common ratio

thus,

and

thus we have two simultaneous equations here, we can solve for and . then we can plug that into the general form to find the nth term

can you continue?

Thx alot, and yes i can continue. Amazing.
