4
pls help

Answer 1

I got 1/4

Answer 2

This is geometric series with first term, a = 256, common ratio, r = 1/2

nth term, an = ar^(n-1)

a_11 = 256(1/2)^10 = 2^8 /2^10

= 1/4 = 0.25

Answer 3

I think is is 1/2

Answer 4

I just worked it out. and I got 1/4 or 0.25

Answer 5

256*1/2 is 128
128*1/2 is 64
64*1/2 is 32

Answer 6

If you do it backwards, you would multiply by 2
so...

32*2=64
64*2=128
128*2=256

Answer 7

So it is 1/2
