WebRatio problem solving. ... The total for the ratio parts needs to be the same, so we scale up using the lowest common multiple. If we write the new ratios onto the line, we can then see what the different sections of the line are. The sections BC will be 21-10=11. WebSo this is a geometric series with common ratio r = −2. (I can also tell that this must be a geometric series because of the form given for each term: as the index increases, each term will be multiplied by an additional factor of −2.). The first term of the sequence is a = −6.Plugging into the summation formula, I get:
