WebFeb 14, 2024 · 1 I need to clarify if the way of working out is correct in finding the common ration by knowing the first term of a geometric series and the sum to infinity. first term: a = 8 sum: S = 400 ratio: r = ? my workings are: S 400 = 8 (1-r∞)/ 1 - r S 400 = 8 / 1 - r 400 * (1 - r) = 8 (1 - r) = 8/400 -r = (8/400) - 1 r = -1 ( (8/400)-1) r = 0.98 WebGeometric sequence. To recall, an geometric sequence or geometric progression is a sequence of numbers where each term after the first is found by multiplying the previous one by a fixed, non-zero number called the common ratio.. Thus, the formula for the n-th term is. where r is the common ratio.. You can solve the first type of problems listed above …

The first term is 80 and we can find the common ratio by dividing a pair of successive terms, 72 80 = 9 10. The n t h term rule is thus a n = 80 ( 9 10) n − 1.
