Answer to: The second term in a geometric sequence is 20. The fourth term in the same sequence is 45/4, or 11.25. What is the common ratio in this...
let us recall what is a geometric sequence. It is a sequence of numbers in which the ratio of every two consecutive numbers is always a constant. For example, 2, 4, 8, 16, ... is a geometric sequence as the common ratio of every two consecutive terms ...
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 ...
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,...
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 thecommon ratioand is ...

Before feeding data into a machine-learning model, it is “vectorized” — converted into numbers representing a point or point sequence in the vector space. The vectors in machine learning signify input data, including bias and weight. In the same way, output from a machine-learning model (...
Step 1: Identify the first term and the common ratioThe first term a of the series is:a=1The common ratio r can be found by dividing the second term by the first term:r=−12 Step 2: Use the formula for the sum of an infinite geometric seriesThe formula for the sum S of an in...
Two consecutive terms of a geometric sequence, in order, are {eq}10 {/eq} and {eq}12 {/eq}. (a) What is the ratio? (b) What is the term before {eq}10 {/eq}? (c) What is the term after {eq}12 ...
