Solution

This is what I can see ok?

\"Write a formula for the general term (the nth term) of the geometric sequence.\"

And then,
fmath-equation-3484C1E6-B0F8-1EC7 ....

as in, the question is not visible.

I am gonna explain it for one problem...

Say, we have the Geo sequence as :

1 , 2, 4 , 8 , 16 , ....

First term, a = 1
Common ratio, r = (2nd term/1st term) or (3rd term/2nd term) and so on....

So, r = 2/1 = 2

So, we have
a = 1
r = 2

And nth term is :
An = a*r^(n-1)

So, for this one, it\'d be :

An = 1(2)^(n-1)

An = 2^(n-1) ----> ANSWER

Kindly attempt this one just like the one above and plz comment if this made sense.

Cheers!
