A geometric sequence forms when there is a common ratio r.
To find the common ratio r, divide a given term by the previous term
So if you picked the second term as the "given term", then...
If you picked the third term as the "given term", then...
The two r values are the same, so we can equate the expressions to get
Now solve the equation for k. I'll let you do this part.
