The demoninator of the fractions are doubling.
So:
1 1/2 1/4 1/8 1/16 1/32 1/64
1/64 or 0.015625

First, you need a way to get a general term, i.e. the nth term. All you have to do is find the pattern.
It seems like the general pattern is 1/2^(n-1), and if we label the sequence in numerical order, we get:
1 ---> 1/2^(1-1) = 1/2^0 = 1 (first term)
2 ---> 1/2^(2-1) = 1/2^1 = 1/2 (second term)
3 ---> 1/2^(3-1) = 1/2^2 = 1/4 (third term)
And now we want the 7th term, so
7 ----> 1/2^(7-1) = 1/2^6 = 1/64 (seventh term)

1 = (1/2)^0
1/2 = (1/2)^1
1/4 = (1/2)^2
See the pattern?
The 7th term will be (1/2)^6 = 1/64

1, 1/2, 1/4, 1/8, 1/16, 1/32, 1/64
1/64
the pattern is multiply by 1/2

this is a G.P. with a=1/2^0
r=1/2
t7=ar^6
=(1/2^0)(1/2)^6
=1/2^6
=1/64
