Answer:
4n+2
Step-by-step explanation:
The common difference between the terms is 4 which means that the sequence is an arithmetic sequence.
The general formula for arithmetic sequence is:

where a_n is the nth term, a_0 is the first term and d is the common difference between them.
We know that

Putting the value in general formula:

So the generalized pattern is 4n+2 ..
Answer:
The supplement is 94
Step-by-step explanation:
Supplementary angles add to 180 degrees
Let x be the supplementary angle
x+86 = 180
Subtract 86 from each side
x+86-86 =180-86
x = 94
Answer: A^2
Step-by-step explanation:
Angle C + Angle B = Angle A
Answer:
Area of the shaded region = 6.88 cm²
Step-by-step explanation:
Area of the shaded region = Area of the rectangle - Area of the semicircle
Area of the rectangle = Length × Width
Length of the rectangle = AD = 8 cm
Width of the rectangle = OP = 4 cm [OP, OB and OC are the radii of the circle which are equal in measures]
Area of the rectangle = 8 × 4 = 32 cm²
Area of the semicircle = 
= 
= 
= 25.12 cm²
Area of the shaded region = 32 - 25.12
= 6.88 cm²
