A geometric series is a sequence in which each term is obtained by multiplying the previous term by a constant ratio. The sum of a geometric series can be calculated using the formula S_n = a * (1 - r^n) / (1 - r), where a is the first term, r is the common ratio, and n...
Similarly, a geometric series is a pattern where any two sequential terms in the series have a common ratio. Example: {eq}-1-2-4\cdots {/eq}. Note that the common ratio between two consecutive terms can be given as {eq}\dfrac{-2}...
