Answer:
<em>summation of five times negative three to the power of n from n equals zero to infinity</em>
Step-by-step explanation:
<u>Summation Notation
</u>
It represents the sum of a finite or infinite number of terms. Let's analyze the terms of the given succession:
5-15+45-135+...
If we take 5 as a common factor, we have
5(1-3+9-27+...)
The parentheses contain the alternate sum/subtraction of powers of 3. The odd terms are positive, the even terms are negative, thus the exponent must be n starting from 0 or n-1 starting from 1
The summation is then represented by

This corresponds with the option:
<u>summation of five times negative three to the power of n from n equals zero to infinity</u>
The answer is c.
When ever it’s a negative slope it’s always a downward line.
And then just see which one makes sense
Could you please mark branliest
The answer would be A-72cm^2
A= 20 let me know if you need an explanation❤️, mark me branliest pls
Answer:
the common ratio is 0.625 or if you prefer 5/8
Step-by-step explanation:
Every geometric sequence has a common ratio which is a constant and is the quotient of any term divided by the term preceding it. In this case:
r=480/768=300/480=187.5/300=0.625
