Answer:
Circumference = PI * diameter
Circumference = 3.14159 * 14
Circumference = 43.98226 inches
Area = PI * radius^2
Area = PI * 7^2
Area = PI * 49
Area = 153.9380400259 square inches

Answer:
Third number is 12
Step-by-step explanation:
Let
be common difference &
be the third number. Set up the following equations:

Solve the simultaneous equation for x-term:

Let’s make sure that we get accurately answer. Substitute x = 12 in any equations which I’ll choose (1):

Now add each terms with common difference as 7:
-2+7 = 5
5+7 = 12
12+7 = 19
19+7 = 26
So our pattern is -2, <u>5</u>, <u>12</u>, <u>19</u>, 26. Since the question only asks for third number then the answer is 12
