The formula to find the sum of a geometric sequence is adding a + ar + ar2 + ar3 + ar4. The sum, to n terms, is given byS(n) = a*(1 - r^n)/(1 - r) or, equivalently, a*(r^n - 1)/(r - 1)
The 99th term would be a times r to the 98th power ,where a is the first term and r is the common ratio of the terms.
The geometric sequence with three terms with a sum of nine and the sum to infinity of 8 is -9,-18, and 36. The first term is -9 and the common ratio is -2.
An arithmetic sequence.

Type yourWhich choice is the explicit formula for the following geometric sequence? answer here...
It is 58465.
200, 20, 2, 0.2 Here you have 4 terms. Add them together, and you find the sum of these four terms. If you need to find the sum of some other terms, i.e 8 terms, then you can use the formula Sn = [a1(r^n - 1/(r - 1) where n = 8, a1 = 200, and r = 1/10.
you must find the pattern of the sequence in order to find the next 50 terms using that pattern and the first part of the sequence given
