<h3>Area of shaded region is 21.5 square centimeter</h3>
<em><u>Solution:</u></em>
The area of the shaded region is equal to the area of the square minus the area of the circle
<em><u>
Find the area of the square</u></em>

Where, "a" is the length of each side
From given figure in question,
a = 10 cm

<em><u>Find the area of circle
</u></em>
The area of the circle is given as:

Where, "r" is the radius of circle
Diameter = 10 cm

Thus,

<em><u>Find the area of the shaded region</u></em>
Area of shaded Region = Area of Square - Area of Circle
Area of shaded Region = 100 - 78.5 = 21.5
Thus area of shaded region is 21.5 square centimeter
Given function: f(x) = (3x+5)/7
y = f(x) so it's the same as y = (3x+5)/7
Swap every copy of x and y to get x = (3y+5)/7
Solve for y to get....
x = (3y+5)/7
7x = 7*(3y+5)/7
7x = 3y+5
7x-5 = 3y+5-5
7x-5 = 3y
3y = 7x-5
3y/3 = (7x-5)/3
y = (7x-5)/3
So the inverse function is f^(-1)(x) = (7x-5)/3

It is arithmetic.
It starts at - 5,
the next item is 0 then 5 and next is 15 ...
============
It isn't geometric. You are not multiplying by 5
The second term must be and not- 5 * 5 = - 25
============
A Fibonacci series adds the previous two terms together to get the next term
Usually it starts at 0, but it doesn't need to.
0,1,1,2,3,5,8,13,21,34 ....
