Not completely sure how to answer your question but all 20 questions where worth 5 points each which she would have gotten a 100 if she got all right but she got 15 which her score would be 75. I think in a ratio of correct to incorrect would be 75:100 , I'm not sure completely.
Answer:
Step-by-step explanation:
So explicit formula essentially is general term formula. Or a formula that when you put in a value for n, you can get that number term in the arithmetic sequence. The way this formula is written is:
Where is the term (result of this formula) that is based on whatever value you put in for n
is the first term of the sequence
n is the term number that you want
and d is the common difference
So to fill in a general formula or explicit formula all we need is and d, because this gives us a general expression for any term we choose, or for any value of n
So to find d, all we have to do is take the difference between a term in front and a term behind that term. Ill show you what I mean:
So if we consider the sequence above we can do
-3 - 3 or -9 - (-3) or 15 - (-9) or -21 -(-15) all of these will give us the value for d (we just take a term before and subtract it by the term after)
So all of these come out to a value of -6
So d = -6
is just our first term so: = 3
Therefore, our explicit formula is
