<u>Arithmetic sequence</u>:-
Step1:
Given sequence is 
Above sequence taking numerator terms
3,6,9,12,15 are in arithmetic progression
First term a= 3 and difference d = 3
now n t h term of given sequence is
now substitute a =3 and d=3
Step2:-
Above sequence taking denominator
4,5,6,7,8...
here a=4 and d=1
Final answer is the general term of given sequence is
The area of the shaded region is 3x^2 + 6x
<h3>How to determine the area of the shaded region?</h3>
The given parameters are:
- Top side of the shaded rectangle = 2x + 7.
- Left side of the shaded rectangle = 2x.
- Top side of the unshaded rectangle = x + 8.
- Left side of the unshaded rectangle = x.
The area of the shaded region is calculated as:
Shaded region area = (Top side of the shaded rectangle * Left side of the shaded rectangle) - (Top side of the unshaded rectangle * Left side of the unshaded rectangle)
Substitute the known values in the above equation
Shaded region area = (2x + 7) * (2x) - (x + 8) * (x)
Evaluate the products
Shaded region area = (4x^2 + 14x) - (x^2 + 8x)
Open the bracket
Shaded region area = 4x^2 + 14x - x^2 - 8x
Collect the like terms
Shaded region area = 4x^2 - x^2 + 14x - 8x
Evaluate the like terms
Shaded region area = 3x^2 + 6x
Hence, the area of the shaded region is 3x^2 + 6x

15) a) -3 and -4
-3(-4) = 12 (two negative numbers multiplied or divided together = positive answer)
b) -5 and 6
6(-5) = -30 (one negative number and one positive number multiplied together = negative answer)
-5 + 6 = 1
16) 2.4 kg, 0.7 kg
c) a loss of 15kg should be your answer, because the loss has a larger number proportion than the gained
