Answer:
Step-by-step explanation:
Adapt the compound amount formula to this situation:
A = P(1 + r)^t becomes A = d(1 + p/100)^1, or just A = d(1 + p/100)
Answer:
The formula for the sequence is:
Step-by-step explanation:
The general term of a geometric sequence is given by:
In which is the first term and r is the common ratio between the terms, that is, the division between them.
What is the formula for the sequence 2, -6, 18, -54, ...?
First term is 2, so
Common ratio is given by:
So the sequence is given by:
Answer:
Step-by-step explanation:
Add 10 to both sides:
Subtract n from both sides:
Divide both sides by 2:
