Which of the following is the missing term of the geometric sequence in which a1= 2 and a3 = 200?
2 answers:
Answer:
20
Step-by-step explanation:
Given that the first term of a geometric sequence is 2 and third term is 200.
We have to find the middle term
A geometric sequence will have terms of the form
Since first term is 2, ...i
Since third term is 200, ...ii
Divide equation ii by i to get
Because increasing sequence, r cannot be negative so only positive value is take.
II term =
Hence missing term is 20

The answer is 5
Here are the steps:
First off, we will be using the distance formula of
So we have the ordered pairs of (3,1) and (6,5)
Once you plug them into the formula it should look like this:
Now we do the math inside the parenthesis and end up with:
Then you multiply by the power and simplify to get:
And the
=5
So your answer is 5
