Answer:

I am assuming you are asking for what percent correct she got. She got 46% correct.

Step-by-step explanation:

You divide the answers correct by the total questions. She got 69 out of 150, so dividing that is .46

To turn a decimal into a percentage, just move the decimal two places to the right, thus getting 46 %

If I assumed what you were asking incorrectly, let me know and I'll be happy to help!

Answer:

Fibonacci Series has been explained and the general term and shortcut to find the corresponding term has been attached

Step-by-step explanation:

Fibonnaci is a beautiful series in mathematics where the term in the series is the sum of the previous two terms of the corresponding term in the series.

Its general form is denoted by

$X_{n} =X_{n-1}+X_{n-2}$ ,

where $X_{n}$ represents the $n^{th}$ of the Fibonnaci series.

The special thing about the Fibonacci series is that the more number of terms we proceed the ratio of the two consecutive term comes closer to the value of the Golden Ratio(φ) whose value is 1.618034.

But there is another method to find out the terms of the the Fibonacci series, which takes into account the value of φ. The formula for the following is as follows
