if the second term of a geometric series is 48 and its fifth term is 6 then find the sum of its first term 6 terms
1 answer:
Answer:
The answer is 189.
Step-by-step explanation:
This geometric sequence is actually just a division of 2 for every term downwards. Therefore, we can see the first term is which is 96. Hence, we can work our way down from there:
<u>List:</u>
First term: 96
Second term: 48
Third term: 24
Fourth term: 12
Fifth term: 6
Sixth term: 3
Now, all we have to do is to add all the first 6 terms together to get:
The answer is 189.

Answer:
Your power function is y=-2
Step-by-step explanation:
The way I found it was.
0=0, so, the function multiply by zero, and have no other term to add
A number (one in a case) gives as a result: -2. So, one, elevated to ANY power results in one, every time. So, I have 1, as a factor and -2 as a result. One is as well a factor that delivers a result equal to the other factor. (3)(1)=3 , (8987)(1)=8987. So, the other factor must be -2
Then I checked all the table, and the results were consistent.
