In a geometric sequence where the terms always increase, the common ratio ( r ) must be greater than 1. This means that each term is obtained by multiplying the previous term by this positive ratio. For example, if the first term is ( a ) and the common ratio is ( r ), the sequence would look like ( a, ar, ar^2, ar^3, \ldots ) with each term growing larger than the last. Thus, the sequence exhibits exponential growth as long as the common ratio remains above 1.
yes
Yes, that's what a geometric sequence is about.
To determine if a sequence is geometric, check if the ratio between consecutive terms is constant. You can calculate the ratio by dividing each term by the preceding term. If this ratio remains the same for all pairs of consecutive terms, then the sequence is geometric. Additionally, a geometric sequence can be verified using a geometric sequence calculator, which will confirm the common ratio and provide further analysis.
The term "0.21525" itself does not indicate whether it is geometric or arithmetic, as it is simply a numerical value. To determine if a sequence or series is geometric or arithmetic, we need to examine the relationship between its terms. An arithmetic sequence has a constant difference between consecutive terms, while a geometric sequence has a constant ratio. If you provide a series of terms, I can help identify its nature.
You mean what IS a geometric sequence? It's when the ratio of the terms is constant, meaning: 1, 2, 4, 8, 16... The ratio of one term to the term directly following it is always 1:2, or .5. So like, instead of an arithmetic sequence, where you're adding a specific amount each time, in a geometric sequence, you're multiplying by that term.
FALSE (Apex)
No, they do not. If the first term is negative, they always decrease.

A descending geometric sequence is a sequence in which the ratio between successive terms is a positive constant which is less than 1.
A static sequence: for example a geometric sequence with common ratio = 1.

A geometric sequence with 5 terms can alternate by having positive and negative terms. For example, one such sequence could be (2, -6, 18, -54, 162). Here, the first term is (2) and the common ratio is (-3), leading to alternating signs while maintaining the geometric property.

The difference between succeeding terms in a sequence is called the common difference in an arithmetic sequence, and the common ratio in a geometric sequence.
