This is a geometric sequence with an initial term of 27 and a common ratio of 1/3
This just means that each term is 1/3 the term preceding it.
Any geometric sequence can be expressed as:
a(n)=ar^(n-1), a=initial term, r=common ratio, n=term number in this case:
a(n)=27(1/3)^(n-1)
<span>17576000 because you can use 26 letters so you multiply that by 3 and get 18576 and then you multiply that by 1000 to get the answer</span>
