Find the common ratio and write out the first four terms of the geometric sequence
9%5E%28n%2B3%29%2F10
=%289%5E4%2F10%299%5E%28n-1%29
=%286561%2F10%299%5E%28n-1%29
=%28656.1%299%5E%28n-1%29
compare to a%5Bn%5D=+a%5B1%5D%2Ar%5E%28n-1%29, you see that first term is a%5B1%5D=656.1 and the common ratio is r=9


a%5B1%5D=656.1
a%5B2%5D=656.1%2Ar%5E1=656.1%2A9=5904.9
a%5B3%5D=656.1%2Ar%5E2=656.1%2A81=53144.1
a%5B4%5D=656.1%2Ar%5E3=656.1%2A729=478296.9
