We need to write the sum in this form:
So, we need to find an appropriate sequence, such that is the i-th even number.
You can easily check that this series is . In fact, you have
and so on. Finally, we have to observe that we want the first 50 elements of this sequence, since .
So, the sum can be written as
Answer:
Step-by-step explanation:
Given
Required
Determine the solution
Since b is a perfect square, the equation can be expressed as:
Apply difference of two squares:
Split:
Remove brackets:
Make a the subject in both equations
The solution can be represented as:
To find FoG ( or F of G) you put the equation of G in for the X of F
FoG =
The domain is All Except 5 since it makes the bottom 0
GoF =
The domain is -Infinity to Infinity
FoG --- The picture --- You want the denominator the same for both of the numbers. By turning 1 into 1x/x it still stays 1 because the x's cancel out, but it can group with the 5.
Next you can multiply both sides (top and bottom) by x and get the final product.
GoF --- Multiply both sides by 5x+1 and get the final product
FoG =
GoF =

Do you mean this? 
I suspect you do therefore I will walk you through the steps and explanations, therefore when you have this answer again, you'd know what to do without doubts!
Firstly, you'd want to make it easier. The easiest way is converting the mixed fraction into a improper fraction. In case you forgotten how to do so, I will list the steps.
Proper/mixed -> Improper:
Improper fractions occur when the top, or numerator, obtains a greater value compared to the denominator, or the number below the bar. However, how do we change a proper or a mixed fraction into such?
1) First you multiply the whole number by the fraction's denominator. In this case 14 by 20, which gets us 280.
2) Secondly, you add that total to the numerator, which would be 280. 280 + 9 = 289.
3) Then you write your result as the numerator, placing it above the bar!
There you have it! 14 9/20 = 289/20
Now, since we changed our proper into an improper total, we can do the next step in our process of converting fractions to decimals. Next, you simply divide the numerator by the denominator as N / D.
This would give us 14.45. 14.45 would be our answer.
