The equation is:
The sum is:
--------------------------------------------------------------------
If the sequence is infinite, the formula is:
-------------------------------------------------------------------
Step-by-step explanation:
We must calculate the radius of the geometric series
The first term of the series is:
The last term of the series is:
If the sequence is finite then the formula is:
If the sequence is infinite then by definition as the radius are then the formula for the sum of the geometric sequence is:
Answer:
Step-by-step explanation:
Quiana has 5 times more text messages from Yolanda than from Pierre, we also know that she actually has 30 text messages from Yolanda. In other words, 30 texts from Yolanda is 5 times more text messages than from Pierre.
Thus, if we call p the number of texts messages from Pierre we would have that
(since 30 texts from Yolanda is 5 times more than p, we can divide by 5 to find p)
And if we solve this equation we would get that Quiana has 6 text messages from Pierre
