Question

Find s_6, the sixth term in the series which corresponds to the geometric sequence which has a=8 and r=1/2

Answer 1

Just multiply each term by 1/2 each time.
The terms are 8,4,2,1, 1/2 and 1/4.
The answer is 1/4.
Another way: The nth term of a geometric sequence
with multiplier r is ar^(n-1).
Where a is the first term.
So in your case r = 1/2 and n = 6, so S_6 = 8*(1/2)^5=
8/32 = 1/4.

Answer 2

8(1/2)^5 = 1/4

Answer 3

1/4

Answer 4

8(1/2) *3
