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: WebSolve the difference equation ( n ≥ 2): Solution. Step 1. Solve the homogeneous difference equation. We know from Chapters 8 and 12 that the yn + 1 = ryn defines a geometric …
WebAnswer. We know that if the common ratio, 𝑟, satisfies 𝑟 < 1, then the sum of an infinite geometric sequence with first term 𝑇 is 𝑆 = 𝑇 1 − 𝑟. ∞. We can see that the first term is 1 3 2, so we will need to calculate the common ratio, 𝑟. We find this by dividing a term by the term that precedes it, so we will use the ... WebA geometric progression is a special type of progression where the successive terms bear a constant ratio known as a common ratio. It is also commonly referred to as GP. The GP is generally represented in form a, ar, ar 2.... where 'a' is the first term and 'r' is the common ratio of the progression.The common ratio can have both negative as well as positive …
