In a geometric sequence, each term is equal to the previous term times a constant, non-zero multiplier called the common factor. Geometric sequences can have a fixed number of terms, or they can be infinite. In either case, the terms of a geometric sequence can rapidly become very large,...
In a geometric sequence, the first term is 2 and the common ratio is 3. What is the 4th term? A. 18 B. 54 C. 16 D. 32 相关知识点: 试题来源: 解析 B。等比数列通项公式为 an = a1×r^(n - 1) ,将 a1 = 2,r = 3,n = 4 代入,可得 a4 = 2×3^(4 - 1) = 54 。
In both math and English, a “sequence” refers to a group of things arranged in some particular order. Outside of math, the things being arranged could be anything—perhaps the sequence of steps in baking a pie. But in math, the things being arranged are usually—no surprise here—number...
A geometric sequence is a sequence of numbers in which each term is obtained by multiplying a fixed number with the previous term, except the first term. In other words, the ratio of any two consecutive numbers in a geometric sequence is equal. This ratio is called the common ratio and ...

When this is the case, investigating the choice of a name can reveal interesting and unforeseen connections among mathematical topics. In this study, we tasked prospective and practicing teachers to consider: What is geometric about geometric sequences? Participants embedded their answers to this ...

As astounding as it may still seem to many, Bell’s theorems do not prove nonlocality. Non separable multipartite objects exist classically, meaning w
In real life, the frequency of the cycles can be a factor, especially if the loading frequency coincides with a natural frequency or resonance of the object which amplifies the magnitude of the cycles. 在真实世界,循环的频率会是一个因素的,特别是载荷施加频率与固有频率一致,或与物体谐振,放大循环...
