I already answered that question, here's the link: brainly.com/question/10534199.
But if you still want the explanation, here it is:
"So if we want to measure probability, you have to add, then divide, like this:
First
, which gives us 18.
Then we see, that 6 is 1/3 of 18, so we conclude. The answer is 33.33%.
Hope this helped!"

This question is incomplete, here is the complete question
What is the recursive formula for this geometric sequence 2, -10, 50, -250, .... ?
The recursive formula for this geometric sequence is:
= 2;
= (-5) •
Step-by-step explanation:
To find the recursive formula for a geometric sequence:
- Determine if the sequence is geometric (Do you multiply, or divide, the same amount from one term to the next?)
- Find the common ratio. (The number you multiply or divide.)
- Create a recursive formula by stating the first term, and then stating the formula to be the common ratio times the previous term.
The recursive formula is:
= first term;
= r •
, where
is the first term in the sequence
is the term before the nth term
- r is the common ratio
∵ The geometric sequence is 2 , -10 , 50 , -250
∴ = 2
- To find r divide the 2nd term by the first term
∵
∴
- Substitute the values of and r in the formula above
∴ = 2;
= (-5) •
The recursive formula for this geometric sequence is:
= 2;
= (-5) •
