This is a geometric progression with a factor of -10, so 0.562.
It is a geometric progression with common ratio 0.5
15. It's a Geometric Progression with a Common Ratio of 1/5 (or 0.2).
Sounds like a Geometric Progression eg 1-3-9-27-81 etc
Yes, that's what a geometric sequence is about.
No.
There are different answers depending upon whether the sequence is an arithmetic progression, a geometric progression, or some other sequence. For example, the sequence 4/1 - 4/3 + 4/5 - 4/7 adds to pi
This is a geometric progression with a factor of -10, so 0.562.
It is not possible to explain because you have not specified the nature of the sequence. A sequence can be an arithmetic, or geometric progression, increasing or decreasing. Or it can be a polynomial or power progression, again increasing or decreasing. Or it can be a sequence of random numbers.

The geometric series is, itself, a sum of a geometric progression. The sum of an infinite geometric sequence exists if the common ratio has an absolute value which is less than 1, and not if it is 1 or greater.
It is a geometric progression with common ratio 0.5
This is referred to as a geometric progression - as opposed to an arithmetic progression, where each new number is achieved via addition or subtraction.
No.
No. It is a sequence for which the rule is a quadratic expression.
