Answer:
The constant factor between consecutive terms of a geometric sequence is called the common ratio.
Example:
To find the common ratio , find the ratio between a term and the term preceding it. r=42=2. 2 is the common ratio.
Answer:
13
Step-by-step explanation:
Let the number be x.
ATQ x+22=455/x. x^2+22x=455. x=-35 or 13. Since x is positive, x=13
I believe the answer is D. because -12 + -1 equal -13
